From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andre Przywara Date: Mon, 17 Dec 2018 10:05:43 +0000 Subject: [U-Boot] [PATCH 0/2] mmc: Fix partition table init regression Message-ID: <20181217100545.28369-1-andre.przywara@arm.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Commit d0851c893706 ("blk: Call part_init() in the post_probe() method") in the 2019.01-rc1 merge window moved the partition init call to the generic DM layer, leaving every non-DM driver behind. As the result all Allwinner boards now don't read the partition table automatically anymore: => fatls mmc 0 ** Unrecognized filesystem type ** => fatload mmc 0 $kernel_addr_r Image-4.20-rc3 ** Unrecognized filesystem type ** A quick workaround is to explicitly read the partition table, but this is still a regression, as it breaks existing scripts and workflows: ========== => mmc part Partition Map for MMC device 0 -- Partition Type: DOS Part Start Sector Num Sectors UUID Type 1 8192 30873600 00000000-01 0c => fatls mmc 0 852304 xen 23544320 Image-4.20-rc3 2 file(s), 0 dir(s) ========== These two patches are the minimal version to fix this problem, by bringing the implicit part_init() call back just for non-DM MMC drivers. Patch 1 is needed to keep the H6 SPL below the size limit. The whole SPL_LIBDISK_SUPPORT symbol is now somewhat obsolete and needs some proper fixing, but this needs more discussion and testing and is probably nothing for this release still. Thanks, Andre.
