2015-02-25sh: enable CONFIG_USE_PRIVATE_LIBGCC by defaultMasahiro Yamada

2015-02-25sh: import missing private libraries from Linux 3.19Masahiro Yamada
SuperH is supposed to support the Private Library feature, but it is actually not working. If CONFIG_USE_PRIVATE_LIBGCC is enabled, the build fails for the undefined references to '__sdivsi3_i4i' and '__udivsi3_i4i'. To fix this error, import missing libraries from Linux 3.19 and adjust them for U-Boot: - Remove "#include <linux/module.h>" and "EXPORT_SYMBOL(...)" - Use SPDX-License-Identifier - Remove white space Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>

2015-02-21bcm2836 SoC support (used in Raspberry Pi 2 model B)Stephen Warren
The bcm2835 and bcm2836 are essentially identical, except: - The CPU is an ARM1176 v.s. a quad-core Cortex-A7. - The physical address of many IO controllers has moved. Rather than introducing a whole new bcm2836 value for $(SOC) or $(ARCH), update the existing bcm2835 code to handle the minor differences, and plumb it into the ARMv7 CPU architecture.

This commit adds $(srctree)/arch/arm/$(machdirs)/include/mach to the headers search path. It allows us to replace "#include <asm/arch/foo.h>" with "#include <mach/foo.h>". As "#include <asm/arch/foo.h>" is still supported, we can modify each file one by one. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2015-02-21ARM: prepare for moving SoC sources into mach-*Masahiro Yamada
In U-boot, the directory structure, arch/$(ARCH)/cpu/$(CPU)/$(SOC)/ has been adopted except that $(CPU) is missing from some architectures and $(SOC) is missing from some CPUs. This structure did not fit very well in some cases. [1] AT91 AT91 SoC family have been developed across some ARM processor generations. Generally speaking, some IPs are often re-used in the same SoC family (same SoC vendor) even when the main processor is updated. As a result, a SoC-common directory is needed in the upper level. Currently, AT91 source files are placed as follows: arch/arm/cpu/arm920t/at91/* arch/arm/cpu/arm926ejs/at91/* arch/arm/cpu/armv7/at91/* arch/arm/cpu/at91-common/* Once directories are split, the motivation for refactorings across CPU directories is lost. Some files in arm920t/at91/ and arm926ejs/at91/ are so similar that they could be merged. [2] Tegra Tegra is a little bit special case where different CPUs are used for SPL and the main U-boot. To obey the arch/$(ARCH)/cpu/$(CPU)/$(SOC) structure, the source files must be placed across the CPUs, again SoC-common directory is necessary in the upper level. Moreover, there are several families in Tegra: Tegra20, Tegra30, Tegra114, Tegra124. Here again, the tegra-common directory is needed to contain commonly-used files. Tegra directories have been sprinkled in the directory structure. arch/arm/cpu/arm720t/tegra20 arch/arm/cpu/arm720t/tegra30 arch/arm/cpu/arm720t/tegra114 arch/arm/cpu/arm720t/tegra124 arch/arm/cpu/arm720t/tegra-common arch/arm/cpu/armv7/tegra20 arch/arm/cpu/armv7/tegra30 arch/arm/cpu/armv7/tegra114 arch/arm/cpu/armv7/tegra124 arch/arm/cpu/armv7/tegra-common arch/arm/cpu/tegra20-common arch/arm/cpu/tegra30-common arch/arm/cpu/tegra114-common arch/arm/cpu/tegra124-common arch/arm/cpu/tegra-common As you see, splitting SoC code by the CPU is not going well, especially for ARM. Why don't we collect SoC-specific files into a single place? A good example we can follow is Linux's arch/arm/mach-* structure. This item was discussed in the following thread: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/188548/ Looks like I got some positive responses and we are almost ready to start this movement. This commit prepares arch/arm/Makefile for describing machdirs in it. After this commit, we can move SoC directory to arch/arm/mach-$(SOC) in simple steps although some cases such as AT91 and Tegra need more fixes. What we generally have to do is: [1] Move files arch/arm/cpu/$(CPU)/$(SOC)/* to arch/arm/mach-$(SOC)/* [2] Add machine entry into arch/arm/Makefile [3] Remove "obj-y += $(SOC)" from arch/arm/cpu/$(CPU)/Makefile [4] Fix the Kconfig file path in arch/arm/Kconfig [5] Modify MAINTAINERS if necessary Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2015-02-16sunxi: Support the FEL boot mode in the regular u-boot buildSiarhei Siamashka
So that the CONFIG_SPL_FEL option is not needed anymore. And the regular SPL binary, generated by the default u-boot build, is now also bootable over USB in the FEL mode. The SPL still can boot from the SD card too. A bunch of system registers need to be saved/restored in order to ensure that the IRQ handler still works in the BROM FEL code after getting control back from the SPL. This is done in the sunxi code instead of abusing ifdefs in 'start.S'. The decision whether to load the main u-boot binary from the SD card or return to the FEL code in the BROM is done at runtime. Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com> [hdegoede@redhat.com: Since we now restore various regs before returning to the FEL BROM code we can drop the sunxi specific #ifdefs in start.S] Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
