Add 'bbram' command which is very convenient tool for examining and modyfying BBRAM content. Examples: Write one byte: $ bbram write backup_regs 0x1 0xaa Write many bytes (starting from 0x13): $ bbram write backup_regs 0x13 0xa 0xb 0xc 0xd 0xe 0xf 0xaa 0xab 0xac Read whole BBRAM: $ bbram read backup_regs Read many bytes (4 bytes starting from address 0x14 in this case): $ bbram read backup_regs 0x14 4 Read one byte (from 0x14 address): $ bbram read backup_regs 0x14 Signed-off-by: Patryk Duda <pdk@semihalf.com>
