2015-02-09microblaze: spl: Do not call mem_malloc_init and use early allocMichal Simek
This patch has some parts connected together: - Use _gd in bss section which is automatically cleared Location at SPL_MALLOC_END wasn't cleared at all - Use MALLOC_F_LEN(early alloc) instead of FULL MALLOC (mem_malloc_init is not called at all) - Simplify malloc and stack init. At the end of SPL addr is malloc area and below is stack Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2015-02-09microblaze: Add support for CONFIG_SYS_MALLOC_F_LENMichal Simek
Create space for dm_init where calloc is called and malloc_base has to be initialized. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2015-02-09microblaze: Do not use CONFIG_SYS_GENERIC_GLOBAL_DATAMichal Simek
Because it is not compatible with DM where malloc_base has to be available early and init has to be done in ASM. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2015-02-09arc: build libgcc in U-BootAlexey Brodkin
This way we may have very limited set of functions implemented so we save some space. Also it allows us to build U-Boot for any ARC core with the same one toolchain because we don't rely on pre-built libgcc. For example: * we may use little-endian toolchain but build U-Boot for ether endianess * we may use non-multilibbed uClibc toolchain but build U-Boot for whatever ARC CPU flavour that current GCC supports Private libgcc built from generic C implementation contributes only 144 bytes to .text section so we don't see significant degradation of size: --->8--- $ arc-linux-size u-boot.libgcc-prebuilt text data bss dec hex filename 222217 24912 214820 461949 70c7d u-boot.libgcc-prebuilt $ arc-linux-size u-boot.libgcc-private text data bss dec hex filename 222361 24912 214820 462093 70d0d u-boot.libgcc-private --->8--- Also I don't notice visible performance degradation compared to pre-built libgcc (where at least "*div*" functions are had-written in assembly) on typical operations of downloading 10Mb uImage over TFTP and bootm.

2015-02-09arc: move CPU flags selection to the main "config.mk"Alexey Brodkin
As a preparation to ARCv2 port submission we're moving CPU slection flags to a common location. Also it will allow us to have more flexible CPU specification, not only ISA version but CPU family as well checking CONFIG_ARC_CPU_xxx. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-02-09arc: move SYS_MONITOR_BASE setup in KonfigAlexey Brodkin
Following SPARK ARC now has SYS_MONITOR_BASE setup via Kconfig. This makes "include/configs/*.h" cleaner and more flexible. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-02-09arc: hard-code CONFIG_ARCH_EARLY_INIT_R in asm/config.hAlexey Brodkin
Common arch_early_init_r() is used in "arc/lib/cpu.c" for all ARC boards so there's no sense in separate per-board definitions. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-02-09arc: get rid of useless CONFIG_SKIP_LOWLEVEL_INITAlexey Brodkin
Currently there's nothing related to really low-level init on ARC so CONFIG_SKIP_LOWLEVEL_INIT definition makes no sense. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-02-09arc: hard-code CONFIG_SYS_GENERIC_BOARD into asm/config.hAlexey Brodkin
There're no other options for ARC except "generic board" so ther's no point to define CONFIG_SYS_GENERIC_BOARD per board. We now have it set fo all ARC boards. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-02-09arc: add selection of endianess in KconfigAlexey Brodkin
This change allows to keep board description clean and minimalistic. This is especially helpful if one board may house different CPUs with different features. It is applicable to both FPGA-based boards or those that have CPUs mounted on interchnagable daughter-boards. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

2015-02-09arc: add more flavours of ARC700 series CPUAlexey Brodkin
Now we may select a particular version of ARC700: * ARC750D or * ARC770D It allows more flexible (or more fine tuned) configuration of U-Boot. Before that change we relied on minimal configuration but now we may use specific features of each CPU. Moreover allows us to escape manual selection of options that exist in both CPUs but may have say different version like MMUv2 in ARC750D vs MMUv3 in ARC770D.

2015-02-09arc: remove CPU hard-coded selection from board description in include/configsAlexey Brodkin

Current the MMC support will enable MCI port A, Which is only exist for 2mmc board. So by default we need to disable MMC (port A) support. And only enable it for 2mmc board.
