The current default of 0x400 for SYS_MALLOC_F_LEN is too small if any additional drivers marked as DM_FLAG_PRE_RELOC are loaded before relocation.
CONFIG_RSA=y which is needed for UEFI secure boot or for FIT image verification loads the driver mod_exp_sw which has DM_FLAG_PRE_RELOC.
CONFIG_LOG=Y is another setting requiring additional early malloc area, cf. log_init().
When running pine64-lts_defconfig with CONFIG_RSA=y and debug UART enabled we see as output in main U-Boot
alloc_simple() alloc space exhaustedWith this patch the default values of SYS_MALLOC_F_LEN is raised to 0x2000. The default for SPL_SYS_MALLOC_F_LEN on ARCH_SUNXI is explicitely set to 0x400 to avoid an increased usage of SRAM on elder SoCs.
