Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2014-11-27MIPS: bootm: add missing initramfs relocationDaniel Schwierzeck
The initramfs is currently only relocated if the user calls the bootm ramdisk subcommand. If bootm should be used without subcommands, the arch-specific bootm code needs to implement the relocation. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2014-11-27MIPS: remove board.cDaniel Schwierzeck
After all MIPS boards are switched to generic-board, the MIPS specific board.c can be removed. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2014-11-27MIPS: fix setup of initial stack frameDaniel Schwierzeck
To get correct stack walking and backtrace functionality in gdb, registers fp and ra should be initialized before calling board_init_f or board_init_r. Thus allocating stack space and zeroing it as it is currently done in board.c becomes obsolete. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

2014-11-23kbuild: Descend into SOC directory from CPU directoryMasahiro Yamada
Some CPUs of some architectures have SOC directories. At present, the build system directly descends into SOC directories from the top Makefile, but it should generally descend into each directory from its parent directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-11-20include: move various macros to include/linux/kernel.hMasahiro Yamada
U-Boot has imported various utility macros from Linux scattering them to various places without consistency. In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN, container_of, DIV_ROUND_UP, etc. In include/linux/compat.h are min_t, max_t, round_up, round_down, etc. We also have duplicated defines of min_t in some *.c files. Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position. Note: This commit simply moves the macros; the macros roundup, min, max, min2, max3, ARRAY_SIZE are different from those of Linux at this point.

2014-11-01MIPS: add .padding section to linker scriptDaniel Schwierzeck
Commit 79fd7e649e287228a1445820a72f7dd33baedb96 MIPS: always keep all sections in u-boot ELF binary. Always keep all sections in u-boot ELF binary. Move all unneeded sections after _end to avoid allocating space in the final binary. Also remove .deadcode section which is now obsolete. removed section .deadcode because the original symptoms were not visible anymore. Unfortuneatly the binutils bug still exists. The size of .rel.dyn section is often bigger than needed for all entries. But objcopy only allocates space as much as required for all reloc entries. Thus there is a gap between the last entry and __rel_dyn_end in u-boot.bin. If u-boot is booted from RAM (e.g. in SPL scenarios) that area could contain garbage data which could lead to CPU exceptions during relocation.

2014-10-23mips: enable CONFIG_USE_PRIVATE_LIBGCC by defaultMasahiro Yamada
Without the private libgcc, we need a full multilib toolchain with different libgcc or multiple toolchains to build all BE/LE and hard-float/soft-float variants of MIPS boards. That is not feasible. This commit allows us to build all the MIPS boards with a single kernel.org toolchain: https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/ x86_64-gcc-4.9.0-nolibc_mips-linux.tar.xz This change sounds reasonable for most users. If necessary, you can disable this option via "make menuconfig" or friends. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2014-09-13kconfig: remove redundant "string" type in arch and board KconfigsMasahiro Yamada
Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME} are specified in arch/Kconfig. We can delete the ones in arch and board Kconfig files. This commit can be easily reproduced by the following command: find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e ' /config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ { N s/\n[[:space:]]*string// } ' Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2014-07-30kconfig: add board Kconfig and defconfig filesMasahiro Yamada
This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

2014-03-07kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCCMasahiro Yamada
Before this commit, USE_PRIVATE_LIBGCC was defined in arch-specific config.mk and referenced in arch/$(ARCH)/lib/Makefile. We are not happy about parsing config.mk again and again. We have to keep the same behavior with a different way. By adding "CONFIG_" prefix, this macro appears in include/autoconf.mk, include/spl-autoconf.mk. (And treating USE_PRIVATE_LIBGCC as CONFIG macro is reasonable enough.) Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes" in arch/arm/cpu/arm720t/tegra*/config.mk, whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk. It means Tegra enables PRIVATE_LIBGCC only for SPL. We can describe the same behavior by adding #ifdef CONFIG_SPL_BUILD # define CONFIG_USE_PRIVATE_LIBGCC #endif to include/configs/tegra-common.h.

2014-02-19kbuild: change out-of-tree buildMasahiro Yamada
This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>
2013-11-26malta: enable PIIX4 SERIRQPaul Burton
Whilst U-boot does not require this itself, Linux currently relies upon it having been muxed and enabled by the bootloader. Thus in order to preserve compatibility with current kernels before a fix is merged in Linux we will enable the SERIRQ interrupt and mux it to its pin. Without doing this current kernels will never receive serial port interrupts and the end result is typically that userland appears to hang. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-26mips: don't hardcode Malta env baudratePaul Burton

2013-11-15malta: use unmapped flash base addressGabor Juhos
The physical base address of the NOR flash is 0x1e000000 on the Malta boards. The hardware also maps the first 4MiB of the flash into the 0x1fc00000-0x1fffffff range. Currently, U-Boot uses the mapped address to access the flash, which does not work in recent qemu versions. Since commit a427338b222b43197c2776cbc996936df0302f51 (mips_malta: correct reading MIPS revision at 0x1fc00010) writing to the mapped address space causes a CPU exception. Due to the exception, U-Boot hangs during boot when it tries to detect the CFI flash chip. Use the correct physical address for the MALTA_FLASH_BASE constant to fix the problem. In order to avoid relocation problems, also update the CONFIG_SYS_{TEXT,MONITOR}_BASE constants. The change makes it possible to start U-Boot on a Malta board emulated with Qemu 1.6.1 and 1.7.0-rc0. It also works on older versions (tested with 1.1.1, 1.2.2, 1.4.2, 1.5.3).

2013-11-09malta: setup PIIX4 interrupt routePaul Burton
Without setting up the PIRQ[A:D] interrupt routes, PCI interrupts will be left disabled. Linux does not set up this routing but relies upon it having been set up by the bootloader, reading back the IRQ lines which the PIRQ[A:D] signals have been routed to. This patch routes PIRQA & PIRQB to IRQ 10, and PIRQC & PIRQD to IRQ 11. This matches the setup used by YAMON. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

2013-11-09malta: support for coreFPGA6 boardsPaul Burton
This patch adds support for running on Malta boards using coreFPGA6 core cards, including support for the msc01 system controller used with them. The system controller is detected at runtime allowing one U-boot binary to run on a Malta with either. Due to the PCI I/O base differing between Maltas using gt64120 & msc01 system controllers, the UART setup is modified slightly. A second UART is added so that there is one pointing at the correct address for each system controller. The Malta board then defines its own default_serial_console function to select the correct one at runtime. The incorrect UART will simply not function. Tested on: - A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both with and without an L2 cache. - QEMU. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09qemu-malta: rename to just "malta"Paul Burton

2013-11-09mips32: detect L1 cache sizes if they're not definedPaul Burton
For boards such as the MIPS Malta with an FPGA core card it is desirable to be able to detect the L1 cache sizes at runtime, since they are not dependant upon the board but on the FPGA bitstream in use. This patch performs that detection when the CONFIG_SYS_[DI]CACHE_SIZE macros are not defined by the board configuration. In cases where the sizes are detected this patch also removes the restriction that the I-cache & D-cache line sizes must be the same, as this is not necessarily true. If the cache sizes are defined by a configuration then they will be hardcoded as before, so this patch will not add overhead to such boards. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

The Qemu specific bootm implementation was intended for a special Qemu target in Linux kernel. But this target has been dropped in v2.6.25-rc1 by commit 302922e5f6901eb6f29c58539631f71b3d9746b8 Author: Ralf Baechle <ralf@linux-mips.org> Date: Tue Jan 29 10:15:02 2008 +0000 [MIPS] Qemu: Remove platform. The Qemu platform was originally implemented to have an easily supportable platform until Qemu reaches a state where it emulates a real world system. Since the latest release Qemu is capable of emulating the MIPSsim and Malta platforms, so this goal has been reached. The Qemu plaform is also rather underfeatured so less useful than a Malta emulation. Thus the special bootm implementation is obsolete by now and can be dropped.
