From c0b417b2f1a313a5fee5d08eda4a886a9950d1ed Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 11 Jan 2021 21:11:39 +0100 Subject: [PATCH] sunxi: support loading with SPL > 32KB H616 supports and needs bigger SPL than 32 KiB, mostly due to big DRAM driver and need for PMIC configuration, which pulls several drivers which are not needed otherwise. spl_mmc_get_uboot_raw_sector() will now compare pre-configured size with that, reported in SPL header. If size in header is bigger, it will use that value instead. In the process of function rework, also add missing function argument.
