* ENGR00174841 [U-Boot]Add a command to erase any pre-saved environmentEric Sun2012-02-27-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A "destroyenv" command is provided to erase any pre-save environment in the boot storage. The command simply add 1 to the CRC section and write it back to the storage. Per the logic of U-Boot, this means after a reset, the software will recognize the stored environment settings as "damaged" and turn to use the default one, which is defined in "default_environment" With this command, platform bring up owner can maintain a "ready-to-use" environment settings in software which others can use very conviniently. U-boot users can also use it to do a environment restore if they want. ----------------------------------- Usage Example: > destroyenv invalidate the CRC write invalidate enviroment data to storage Erasing SPI flash...Erasing SPI NOR flash 0xc0000 [0x2000 bytes] ..SUCCESS Writing to SPI flash...Writing SPI NOR flash 0xc0000 [0x2000 bytes] <- ram 0x276009b8 SUCCESS done > ----------------------------------- Signed-off-by: Eric Sun <jian.sun@freescale.com>

* compiler.h: unify system ifdef cruft hereMike Frysinger2009-07-19-5/+1
| | | | | | | | | | | Shove a lot of the HOSTCC and related #ifdef checking crap into the new compiler.h header so that we can keep all other headers nice and clean. Also introduce custom uswap functions so we don't have to rely on the non standard implementations that a host may (or may not in the case of OS X) provide. This allows mkimage to finally build cleanly on an OS X system. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* mflash: Initial mflash supportunsik Kim2009-04-03-0/+12
| | | | | | | | | | | | | | | | | | | | Mflash is fusion memory device mainly targeted consumer eletronic and mobile phone. Internally, it have nand flash and other hardware logics and supports some different operation (ATA, IO, XIP) modes. IO mode is custom mode for the host that doesn't have IDE interface. (Many mobile targeted SoC doesn't have IDE bus) This driver support mflash IO mode. Followings are brief descriptions about IO mode. 1. IO mode based on ATA protocol and uses some custom command. (read confirm, write confirm) 2. IO mode uses SRAM bus interface. Signed-off-by: unsik Kim <donari75@gmail.com>

* crc32: use uint32_t rather than unsigned longMike Frysinger2008-04-24-3/+8
| | | | | | | | | | | | | The envcrc.c does sizeof(unsigned long) when calculating the crc, but this is done with the build toolchain instead of the target tool chain, so if the build is a 64bit system but the target is 32bits, the size will obviously be wrong. This converts all unsigned long stuff related to crc32 to uint32_t types. Compile tested only: output of ./tools/envcrc when run on a 32bit build system matches that of a 64bit build system.

* [PATCH] Select NAND embedded environment from board configurationStefan Roese2006-11-27-2/+1
| | | | | | | | | | The current NAND Bootloader setup forces the environment variables to be in line with the bootloader. This change enables the configuration to be made in the board include file instead so that it can be individually enabled.
