From a91998d8affc0405bafeade583204f66db81e252 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= Date: Sun, 3 Apr 2022 00:17:00 +0200 Subject: [PATCH] mmc: fsl_esdhc_spl: pre-PBL: fix determining U-Boot size MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In pre-PBL header is stored size of code which BootROM copies from SD card to L2/SRAM. This size has upper limit of L2 cache size. In most cases this is size of U-Boot SPL or size of L2 cache. Therefore this size in pre-PBL header cannot be used for determining size of proper U-Boot. So always use CONFIG_SYS_MMC_U_BOOT_SIZE for determining size of proper U-Boot which stored on SD card.
