Up until now, the R5 SPL in J722S platform was configured to start out of the SMS0_HSM_SRAM0_0 (0x0043C00000, 512KB) memory region. However, with the requirement of loading HSM M4F core with its own secure firmware, R5 SPL can no longer utilize that memory to execute itself.
Therefore, utilize the MSRAM8KX256E0_RAM (0x0043C40000, 256KB) memory region for loading and executing R5 SPL. Naturally, the SPL size has now to be trimmed to be fit inside the smaller 256KB region. As an example, create a new defconfig (j722s_evm_r5_hsmboot_defconfig) which removes the SPI related configs to trim down the SPL size to ~175KB. The above defconfig demonstrates loading HSM core with SD, eMMC and UART bootmodes. Signed-off-by: Beleswar Padhi <[email protected]> --- v3: Changelog: 1. New patch.
