The current uboot default config for the A13 SOM erroneously enables support for the AXP209 power regulator IC which is not present on the board. This superfluous support module sets an incorrect initial clock frequency and confuses the kernel, ultimately leading to a boot failure later on. Properly disable the PMIC support and enable the EHCI support by translating the deprecated SYS_EXTRA_OPTIONS values into proper SUNXI_NO_PMIC and USB_EHCI_HCD symbols respectively. Also rename 002-add-olimex-a13-som.diff to 002-add-olimex-a13-som.patch and refresh the remaining patches of the series while we're at it.

Subject: [PATCH] sunxi: Fix gmac not working due to cpu_eth_init no longer
|
|
being called
|
|
|
|
cpu_eth_init is no longer called for dm enabled eth drivers, this
|
|
was causing the sunxi gmac eth controller to no longer work in u-boot.
|
|
|
|
This commit fixes this by calling the clock, reset and pinmux setup
|
|
function from s_init() and enabling the phy power pin (if any) from
|
|
board_init().
|
|
|
|
The enabling of phy power cannot be done from s_init because it uses dm
|
|
and dm is not ready yet at this point.
|
|
|
|
Note that the mdelay is dropped as the phy gets enabled much earlier
|
|
now, so it is no longer needed.
