2017-11-21env: Remove CONFIG_ENV_AES supportTom Rini
This support has been deprecated since v2017.09 due to security issues. We now remove this support. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // <smpl> @@@@ -error +pr_err (...) // </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org> [trini: Re-run Coccinelle] Signed-off-by: Tom Rini <trini@konsulko.com>
2017-08-20env: Replace all open-coded gd->env_valid values with ENV_ flagsSimon Glass
Some of these were missed in the conversion. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-08-16env: Rename some other getenv()-related functionsSimon Glass
We are now using an env_ prefix for environment functions. Rename these other functions as well, for consistency: getenv_vlan() getenv_bootm_size() getenv_bootm_low() getenv_bootm_mapsize() env_get_default() Suggested-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Simon Glass <sjg@chromium.org>
2017-08-16env: Rename getenv_hex(), getenv_yesno(), getenv_ulong()Simon Glass
We are now using an env_ prefix for environment functions. Rename these for consistency. Also add function comments in common.h. Suggested-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Simon Glass <sjg@chromium.org>
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: Drop env_relocate_spec() in favour of env_load()Simon Glass
This is a strange name for a function that loads the environment. There is now only one implementation of this function, so use the new env_load() function directly instead. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2017-08-15env: Drop env_get_char_spec()Simon Glass
We only have a single implementation of this function now and it is called env_get_char(). Drop the old function and the weak version. Reviewed-by: Tom Rini <trini@konsulko.com> Signed-off-by: Simon Glass <sjg@chromium.org>
2017-08-15env: common: Drop env_get_char_memory()Simon Glass
This function is the same as env_get_char_spec() apart from dropping the brackets. Drop the brackets from env_get_char_spec() and use that instead of env_get_char_memory(). Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2017-08-15env: common: Drop env_get_char_init()Simon Glass
This function does nothing but call env_get_char_spec(). Drop it and adjust its only caller. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2017-08-15env: common: Factor out the common env_valid checkSimon Glass
The check for gd->env_valid is used in both the 'if' and 'else' part of env_get_char(). Move it into that function instead for simplicity. Drop that code from the two leaf functions. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2017-08-15env: common: Drop env_get_addr()Simon Glass
This function is not used anywhere other than env_get_char(). Move the code into that function. Reviewed-by: Tom Rini <trini@konsulko.com> Signed-off-by: Simon Glass <sjg@chromium.org>
2017-08-15env: common: Make env_get_addr/get_char_memory() staticSimon Glass
These functions are not used outside this file. Make them static and order them to avoid forward declarations. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2017-08-15Move environment files from common/ to env/Simon Glass
About a quarter of the files in common/ relate to the environment. It seems better to put these into their own subdirectory and remove the prefix. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
