[U-Boot] [PATCH 0/2] Fix boot in some am335x sk boards

[Faiz Abbas]

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.

  gpio: omap_gpio: Add DM_FLAG_PRE_RELOC flag
  configs: am335x_evm: Increase SPL_SYS_MALLOC_F_LEN to accomodate
    gpio_devices

[U-Boot] [PATCH 1/2] gpio: omap_gpio: Add DM_FLAG_PRE_RELOC flag

[Faiz Abbas]

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.

[U-Boot] [PATCH 2/2] configs: am335x_evm: Increase SPL_SYS_MALLOC_F_LEN to accomodate gpio_devices

[Faiz Abbas]

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.
