Do you have a patch? That would be very useful.
Seems like debugging in uncompressor was broken some time ago:
config DEBUG_UNCOMPRESS
bool
depends on ARCH_MULTIPLATFORM || PLAT_SAMSUNG ||
ARM_SINGLE_ARMV7M
default y if DEBUG_LL && !DEBUG_OMAP2PLUS_UART &&
(!DEBUG_TEGRA_UART || !ZBOOT_ROM)
&& \!DEBUG_BRCMSTB_UART

RAM size should be ok... how do I check for OMAP HS problems?
