[U-Boot] [PATCH 0/2] Fix boot in some am335x sk boards
am335x standard kit boards with rev >= 1.2A require gpio support to enable DDR in SPL. This was failing because gpio drivers were not getting bound to the gpio devices in SPL.
These patches fix this issue.
Faiz Abbas (2): gpio: omap_gpio: Add DM_FLAG_PRE_RELOC flag configs: am335x_evm: Increase SPL_SYS_MALLOC_F_LEN to accomodate gpio_devices

With DM enabled in SPL, DM_FLAG_PRE_RELOC is required for the omap_gpio driver to be bound to the gpio devices.
Therefore, add DM_FLAG_PRE_RELOC flag to the omap_gpio driver.

Applied to u-boot/master, thanks!
With gpio devices getting created in SPL, the size of the heap is no longer sufficient. Therefore, increase SPL_SYS_MALLOC_F_LEN to 0x1000.
