tools/env: Fix environment size and CRC on 64-bit hosts

2014-11-07T21:27:07Z

On architectures where 'long' is 64 bit, the u-boot environment as seen by the fw_env tools was missing 4 bytes. This patch fixes getenvsize(), and thus also ensures that the environment's CRC32 checksum is calculated correctly. Signed-off-by: Dominic Sacré Cc: Wolfgang Denk Cc: Tom Rini

fw_env.c: Switch get_config to use '%ms' in sscanf

2014-04-17T18:39:54Z

We currently limit ourself to 16 characters for the device name to read the environment from. This is insufficient for /dev/mmcblk0boot1 to work for example. Switch to '%ms' which gives us a dynamically allocated buffer instead. We're short lived enough to not bother free()ing the buffer. Signed-off-by: Tom Rini

env: Implement support for AES encryption into fw_* tools

2014-03-21T20:44:08Z

Implement support for encrypting/decrypting the environment block into the tools/env/fw_* tools. The cipher used is AES 128 CBC and the implementation depends solely on components internal to U-Boot. To allow building against the internal AES library, the library did need minor adjustments to not include U-Boot's headers which are not wanted to be included and define missing types.

fw_env: correct writes to devices with small erase blocks

2014-03-12T21:04:29Z

Some NOR flash devices have a small erase block size. For example, the Micron N25Q512 can erase in 4K blocks. These devices expose a bug in fw_env.c where flash_write_buf() incorrectly calculates bytes written and attempts to write past the environment sectors. Luckily, a range check prevents any real damage, but this does cause fw_setenv to fail with an error. This change corrects the write length calculation. The bug was introduced with commit 56086921 from 2008 and only affects configurations where the erase block size is smaller than the total environment data size. Signed-off-by: Dustin Byford

fw_env: calculate default number of env sectors

2014-03-12T21:04:28Z

The assumed number of environment sectors (always 1) leads to an incorrect top_of_range calculation in fw.env.c when a flash device has an erase block size smaller than the environment data size (number of environment sectors > 1). This change updates the default number of environment sectors to at least cover the size of the environment. Also corrected a false statement about the number of sectors column in fw_env.config.
