Re: [U-Boot] [PATCH] mx51evk: Add CONFIG_REVISION_TAG

Hi Benoît ,

Is this enough? Looking at FSL U-boot there is also a:

static inline void set_board_rev(void) { if ((__REG(GPIO1_BASE_ADDR + 0x0) & (0x1 << 22)) == 0) system_rev |= BOARD_REV_2_0 << BOARD_VER_OFFSET;

}

On mx53loco I had very weird problems when kernel was running and it took me sometime to find out that it was due to wrong detection of the board revision, so I suggest to double check this to avoid this kind of problem on mx51evk too.
