The failure is probably due to some drivers that Tegra uses are not
properly written, ie: these drivers are declared via U_BOOT_DRIVER
with flags DM_FLAG_PRE_RELOC yet it was never working (bound before
relocation) until patch (1) & (2). Now these drivers get bound before
relocation but they were never bound before (assume they were never
required before relocation), so we should identify which driver were
wrongly written, but as a quick solution, can you please enlarge the
CONFIG_SYS_MALLOC_F_LEN of your board and have a try?
