spl: nand: Set bl_len to page size 2023-11-16T17:43:48+00:00 Sean Anderson seanga2@gmail.com 2023-11-04T20:37:44+00:00 38ef64e6ce3d1f84478c6d2700e4d76f80cfcaf4 Since commit 34793598c83 ("mtd: nand: mxs_nand_spl: Remove the page aligned access") there are no longer any users of nand_get_mtd. However, it is still important to know what the page size is so we can allocate a large-enough buffer. If the image size is not page-aligned, we will go off the end of the buffer and clobber some memory. Introduce a new function nand_page_size which returns the page size. For most drivers it is easy to determine the page size. However, a few need to be modified since they only keep the page size around temporarily. It's possible that this patch could cause a regression on some platforms if the offset is non-aligned and there is invalid address space immediately before the load address. spl_load_legacy_img does not (except when compressing) respect bl_len, so only boards with SPL_LOAD_FIT (8 boards) or SPL_LOAD_IMX_CONTAINER (none in tree) would be affected. defconfig CONFIG_TEXT_BASE ======================= ================ am335x_evm 0x80800000 am43xx_evm 0x80800000 am43xx_evm_rtconly 0x80800000 am43xx_evm_usbhost_boot 0x80800000 am43xx_hs_evm 0x80800000 dra7xx_evm 0x80800000 gwventana_nand 0x17800000 imx8mn_bsh_smm_s2 0x40200000 All the sitara boards have DDR mapped at 0x80000000. gwventana is an i.MX6Q which has DDR at 0x10000000.

All supplied callback methods in U-Boot do nothing, but the mtd_erase_callback() function was (until previous patch) grossly abused in U-Boot's mtdpart implementation for completely different purpose.
