> Subject: [U-Boot] [PATCH 03/13] gpio: Remove DM_FLAG_PRE_RELOC flag in > various drivers > > When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be bound before > relocation. 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 <bmeng...@gmail.com> > --- > > drivers/gpio/omap_gpio.c | 2 ++ > drivers/gpio/stm32f7_gpio.c | 2 +- > drivers/gpio/tegra186_gpio.c | 1 - > drivers/gpio/tegra_gpio.c | 1 - > 4 files changed, 3 insertions(+), 3 deletions(-) > Applied to u-boot-dm/master, thanks! _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
