From d0851c8937067ad396f2bdafc46d0326bf3317db Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Mon, 15 Oct 2018 02:21:07 -0700 Subject: blk: Call part_init() in the post_probe() method part_init() is currently called in every DM BLK driver, either in its bind() or probe() method. However we can use the BLK uclass driver's post_probe() method to do it automatically. Update all DM BLK drivers to adopt this change.

However due to a bug in the DM core, the flag only takes effect when devices are statically declared via U_BOOT_DEVICE(). This bug has been fixed recently by commit "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()", but with the fix, it has a side effect that all existing drivers that declared DM_FLAG_PRE_RELOC flag will be bound before relocation now. This may expose potential boot failure on some boards due to insufficient memory during the pre-relocation stage. To mitigate this potential impact, the following changes are implemented: - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver only supports configuration from device tree (OF_CONTROL) - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device is statically declared via U_BOOT_DEVICE() - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Signed-off-by: Bin Meng Reviewed-by: Simon Glass --- drivers/mmc/omap_hsmmc.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'drivers/mmc') diff --git a/drivers/mmc/omap_hsmmc.c b/drivers/mmc/omap_hsmmc.c index ec853d063f..5cb97eb02a 100644 --- a/drivers/mmc/omap_hsmmc.c +++ b/drivers/mmc/omap_hsmmc.c @@ -1953,6 +1953,8 @@ U_BOOT_DRIVER(omap_hsmmc) = { .ops = &omap_hsmmc_ops, .probe = omap_hsmmc_probe, .priv_auto_alloc_size = sizeof(struct omap_hsmmc_data), +#if !CONFIG_IS_ENABLED(OF_CONTROL) .flags = DM_FLAG_PRE_RELOC, +#endif }; #endif -- cgit v1.2.1
