2016-01-14arm: move gd handling outside of C codeAlbert ARIBAUD
As of gcc 5.2.1 for Thumb-1, it is not possible any more to assign gd from C code, as gd is mapped to r9, and r9 may now be saved in the prolog sequence, and restored in the epilog sequence, of any C functions. Therefore arch_setup_gd(), which is supposed to set r9, may actually have no effect, causing U-Boot to use a bad address to access GD. Fix this by never calling arch_setup_gd() for ARM, and instead setting r9 in arch/arm/lib/crt0.S, to the value returned by board_init_f_alloc_reserve().

2016-01-14Fix board init code to respect the C runtime environmentAlbert ARIBAUD
board_init_f_mem() alters the C runtime environment's stack it is actually already using. This is not a valid behaviour within a C runtime environment. Split board_init_f_mem into C functions which do not alter their own stack and always behave properly with respect to their C runtime environment.

2016-01-05powerpc, mpc5xxx: fix missing bootflag initHeiko Schocher
since: commit: f05ad9ba "Add a way to skip relocation" tqm5200s board fails to boot. Reason is that board_init_f has a function parameter bootflag, which is not setup in in arch/powerpc/cpu/mpc5xxx/start.S _start So board_init_f gets a undefined bootflag, currently the gd pointer address. Unfortunately this address sets the GD_FLG_SKIP_RELOC bit, so u-boot code gets not relocated and u-boot does not boot ... Init bootflag with 0, and tqm5200 boots fine again.

2015-12-22ARM: uniphier: set DTB file name to fdt_file environmentMasahiro Yamada
When we want to boot Linux with a DTB file downloaded from a TFTP server or somewhere, we need to know the file name to be downloaded. Assume the U-Boot configuration is shared among some similar boards. If they are similar enough, the difference only appears in device trees. The build procedure would be like this: - Board A: make foo_common_defconfig && make DEVICE_TREE=foo_board_a - Board B: make foo_common_defconfig && make DEVICE_TREE=foo_board_b - Board C: make foo_common_defconfig && make DEVICE_TREE=foo_board_c In this case, the U-Boot image contains nothing about the DTB file name it is running with. (CONFIG_DEFAULT_DEVICE_TREE is not helpful for this purpose because it is painful to change it from "make menuconfig" for each board.) This commit allows to lookup the DTB file name based on the compatible string and set it to "fdt_file" environment. Then "tftpboot $fdt_file" will download the file we want.
