2012-09-18env: make "env default" selective, check and applyGerlando Falauto
Change the syntax (user API) for "env default": -f: override write-once variables var... : accept individual variable(s) -a: all (resetting the whole env is NOT the default behavior) Enable variable checking and make changes effective by enabling do_apply argument to himport_r().

2012-09-18env: add check/apply logic to himport_r()Gerlando Falauto
Change hashtable so that a callback function will decide whether a variable can be overwritten, and possibly apply the changes. So add a new field to struct hsearch_data: o "apply" callback function to check whether a variable can be overwritten, and possibly immediately apply the changes; when NULL, no check is performed. And a new argument to himport_r(): o "do_apply": whether to call the apply callback function NOTE: This patch does not change the current behavior.

2012-09-18env: make himport_r() selective on variablesGerlando Falauto

2012-09-18env: unify logic to check and apply changesGerlando Falauto
The logic of checking special parameters (e.g. baudrate, stdin, stdout, for a valid value and/or whether can be overwritten) and applying the new value to the running system is now all within a single function env_check_apply() which can be called whenever changes are made to the environment, no matter if by set, default or import. With this patch env_check_apply() is only called by "env set", retaining previous behavior. Signed-off-by: Gerlando Falauto <gerlando.falauto@keymile.com> Reviewed-by: Marek Vasut <marex@denx.de>
2012-09-18env: cosmetic: drop assignment i = iomux_doenv()Gerlando Falauto
iomux_doenv() can only return 0 or 1. So there is no need to save its return value in variable i, as checking its truth value within an if statement is enough. Signed-off-by: Gerlando Falauto <gerlando.falauto@keymile.com> Reviewed-by: Marek Vasut <marex@denx.de>

2012-09-18env_nand: fix incorrect size parameter to ALLOC_CACHE_ALIGN_BUFFERStephen Warren
The third parameter to ALLOC_CACHE_ALIGN_BUFFER is not size (as named), but rather count (number of elements of the type to allocate). The current code ends up allocating one copy of env_t for each byte in its size, which quite possibly ends up overflowing RAM. This fixes a bug in commit 3801a15 "env_nand: align NAND buffers".

2012-09-18spl: remove forced linking of commands into SPLTyler Olmstead
Remove linker command line options from the SPL makefile that force the inclusion of unreferenced command code from linked object files. As commands are not used in the SPL, these options resulted in an unnecessary increase in the image size, in addition to introducing the possibility of tricky link errors in the case where the command code contained symbols that were not resolved by linking in the limited objects compiled in the SPL build.

2012-09-17mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driverMarek Vasut
This is based on Linux kernel -next: commit 14f44abf1dafc20ba42ce8616a8fc8fbd1b3712b Author: Brian Norris <computersforpeace@gmail.com> Date: Fri Jul 13 09:28:24 2012 -0700 mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It silently masks off at least one flag that might be set by the driver (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly others. Really, as long as driver writers exercise a small amount of care with NAND_* options, this mask is not necessary at all; it was only here to prevent certain options from accidentally being set by the driver. But the original thought turns out to be a bad idea occasionally. Thus, kill it. Note, this patch fixes some major gpmi-nand breakage.
