2017-08-16env: Rename getenv/_f() to env_get()Simon Glass
We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

2017-08-15env: Convert CONFIG_ENV_IS_IN... to a choiceSimon Glass
At present we support multiple environment drivers but there is not way to select between them at run time. Also settings related to the position and size of the environment area are global (i.e. apply to all locations). Until these limitations are removed we cannot really support more than one environment location. Adjust the location to be a choice so that only one can be selected. By default the environment is 'nowhere', meaning that the environment exists only in memory and cannot be saved. Also expand the help for the 'nowhere' option and move it to the top since it is the default.

2017-07-27mips: spl: configure SYS_MALLOC_F_LEN independently for SPL and full U-BootAndy Yan
Some platforms have very limited SRAM to run SPL code, so there may not be the same amount space for a malloc pool before relocation in the SPL stage as the normal U-Boot stage. Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.

2017-07-25Convert CONFIG_ENV_IS_IN_FLASH to KconfigSimon Glass

2017-07-25Convert CONFIG_ENV_IS_IN_MMC/NAND/UBI and NOWHERE to KconfigSimon Glass
This converts the following to Kconfig: CONFIG_ENV_IS_IN_MMC CONFIG_ENV_IS_IN_NAND CONFIG_ENV_IS_IN_UBI CONFIG_ENV_IS_NOWHERE In fact this already exists for sunxi as a 'choice' config. However not all the choices are available in Kconfig yet so we cannot use that. It would lead to more than one option being set. In addition, one purpose of this series is to allow the environment to be stored in more than one place. So the existing choice is converted to a normal config allowing each option to be set independently. There are not many opportunities for Kconfig updates to reduce the size of this patch. This was tested with ./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC And then manual updates. This is because for CHAIN_OF_TRUST boards they can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic now.

2017-07-25MIPS: bootm: Fix broken boot_env_legacy codepathZubair Lutfullah Kakakhel
This patch fixes 2 bugs introduced by the following commit 2bb5b63 MIPS: bootm: rework and fix broken bootm code The CONFIG_IS_ENABLED macro prepends 'CONFIG_' Hence, remove CONFIG_ from CONFIG_MIPS_BOOT_ENV_LEGACY usage. Also, 2bb5b63 reworks bootm so that linux_env_legacy runs before linux_cmdline_legacy. However, linux_env_legacy depends on linux_cmdline_legacy running first as linux_cmdline_init initialilzes linux_argp which linux_env_legacy later depends on during its initialization. Reorder the code so that linux_cmdline_legacy runs before linux_env_legacy. Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com>
2017-07-25MIPS: Stop building position independent codePaul Burton
U-Boot has up until now built with -fpic for the MIPS architecture, producing position independent code which uses indirection through a global offset table, making relocation fairly straightforward as it simply involves patching up GOT entries. Using -fpic does however have some downsides. The biggest of these is that generated code is bloated in various ways. For example, function calls are indirected through the GOT & the t9 register: 8f998064 lw t9,-32668(gp) 0320f809 jalr t9 Without -fpic the call is simply: 0f803f01 jal be00fc04 <puts> This is more compact & faster (due to the lack of the load & the dependency the jump has on its result). It is also easier to read & debug because the disassembly shows what function is being called, rather than just an offset from gp which would then have to be looked up in the ELF to discover the target function. Another disadvantage of -fpic is that each function begins with a sequence to calculate the value of the gp register, for example: 3c1c0004 lui gp,0x4 279c3384 addiu gp,gp,13188 0399e021 addu gp,gp,t9 Without using -fpic this sequence no longer appears at the start of each function, reducing code size considerably. This patch switches U-Boot from building with -fpic to building with -fno-pic, in order to gain the benefits described above. The cost of this is an extra step during the build process to extract relocation data from the ELF & write it into a new .rel section in a compact format, plus the added complexity of dealing with multiple types of relocation rather than the single type that applied to the GOT. The benefit is smaller, cleaner, more debuggable code. The relocate_code() function is reimplemented in C to handle the new relocation scheme, which also makes it easier to read & debug. Taking maltael_defconfig as an example the size of u-boot.bin built using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils 2.24.90) shrinks from 254KiB to 224KiB.
