Old bootloader (same ones which have DT disabled) don't perform any PCIe initialization. The consequence is a freeze during PCIe bring-up on these old u-boot. Same kernel with a newer bootloaders works fine as they contain the corresponding PCIe init code. In this change, we'll add the missing init and make sure the kernel doesn't rely on some preexisting init to get PCIe to work. That includes the following changes: *GPIOs: set function & drive strength *Clocks: add init code for aux & ref clocks *PCIe driver: additional init of the hardware controller Tested 3.18 and 4.1 on an AP148 with bootloader branch 0.0.1 Signed-off-by: Mathieu Olivari <mathieu@codeaurora.org> SVN-Revision: 46557 |
