MLK-10958 imx: mx6ul support Bus Encryption Engine
This patch is to support Bus Encryption Engine(BEE) for i.MX 6UL.
Supported feature:
1. SNVS key and soft key
2. CTR and ECB mode
3. Specify address region to bee.
Two commands are included:
bee init [key] [mode] [start] [end] - BEE block initial
"Example: bee init 1 1 0x80000000 0x80010000\n"
bee test [region]
"Example: bee test 1\n"
Mapping:
[0x10000000 - (0x10000000 + size - 1)] : [start - (start + size - 1)]
[0x30000000 - (0x30000000 + IRAM_SIZE - 1)] : [IRAM_BASE_ADDR -
(IRAM_BASE_ADDR + IRAM_SIZE - 1)]
Whatever start is, start - (start + size -1) will be fixed mapping to
0x10000000 - (0x10000000 + size - 1)
Since default AES region's protected size is SZ_512M, so
on mx6ul evk board, you can not simply run 'bee init', it will
overlap with uboot execution environment, you can use
'bee init 0 0 0x80000000 0x81000000'.
If want to use bee, Need to define CONFIG_CMD_BEE in board configuration
header file, since CONFIG_CMD_BEE default is not enabled.
