Hi,

I seem to understand that remapping, being a CPU specific and depending on a way U-Boot starts (either from ROM or RAM), is taken away in 'lowlevel_init' function, defined either in in $(uboot)/cpu/arm/$(soc)/lowlevel_init.S (for example, $(uboot)/cpu/arm920t/ks8695/) or in $(uboot)/board/board_name/lowlevel_init.S, but what confuses me is that I couldn't find remap functions on every ARM platform, running from ROM at reset.

U wouldnt see mapping the vector on (most) ARM Platforms because they use u-boot as secondary bootloader Initial Arm Bootmonitor would run & that would re-locate the U-boot to ram & then give control to u-boot

I said "most" because ARM Integrator Board doesnt use Arm Bootmonitor & hence its code has remapping functionality.

Kindly look at $(uboot)/board/integratorcp/lowlevel_init.S & $(uboot)/board/integratorcp/integratorcp.c. It needs CONFIG_CM_REMAP setting to be defined

For the board that i am using, i had to make use of this.

Hope this helps
