* sunxi: Properly announce BOOT_DEVICE_BOARD as "FEL"Bernhard Nortmann2016-05-251-0/+9
| | | | | | | | | | | This addresses a cosmetic issue when booting a sunxi device over USB (FEL mode), where the SPL currently would just print "Trying to boot from ". The patch fixes that to properly read "Trying to boot from FEL".

* arm/arm64: Move barrier instructions into separate headerAndre Przywara2016-05-121-1/+1
| | | | | | | | | | | | | | | | Commit bfb33f0bc45b ("sunxi: mctl_mem_matches: Add missing memory barrier") broke compilation for the Pine64, as dram_helper.c now includes <asm/armv7.h>, which does not compile on arm64. Fix this by moving all barrier instructions into a separate header file, which can easily be shared between arm and arm64. Also extend the inline assembly to take the "sy" argument, which is optional for ARMv7, but mandatory for v8. This fixes compilation for 64-bit sunxi boards (Pine64).

* sunxi: mctl_mem_matches: Add missing memory barrierHans de Goede2016-04-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | We are running with the caches disabled when mctl_mem_matches gets called, but the cpu's write buffer is still there and can still get in the way, add a memory barrier to fix this. This avoids mctl_mem_matches always returning false in some cases, which was resulting in: U-Boot SPL 2015.07 (Apr 14 2016 - 18:47:26) DRAM: 1024 MiB U-Boot 2015.07 (Apr 14 2016 - 18:47:26 +0200) Allwinner Technology CPU: Allwinner A23 (SUN8I) DRAM: 512 MiB Where 512 MiB is the right amount, but the DRAM controller would be initialized for 1024 MiB.

* sunxi: Add INITIAL_USB_SCAN_DELAY Kconfig optionHans de Goede2016-04-121-0/+7
| | | | | | | | | Some boards have on board usb devices which need longer than the USB spec's 1 second to connect from board powerup. Add a config option which when non 0 adds an extra delay before the first usb bus scan. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* sunxi: Add support for Allwinner A64 SoCsSiarhei Siamashka2016-04-013-1/+32
| | | | | | | | | | | | | | | The Allwinner A64 SoC is used in the Pine64. This patch adds all bits necessary to compile U-Boot for it running in AArch64 mode. Unfortunately SPL is not ready yet due to legal problems, so we need to boot using the binary boot0 for now.

* sunxi: Explicitly cast u32 pointer conversionsAlexander Graf2016-04-013-4/+4
| | | | | | | | | | | Some parts of the sunxi code cast explicitly between u32 values and pointers. This is not a problem in practice, because all 64bit SoCs today only use the lower 32 bits for their phyical address space. But we need to make sure that the compiler is sure this is not an accident as well.

* sunxi: Move cpu independent code to mach directoryAlexander Graf2016-04-0121-0/+4973
Some of the code in arch/arm/cpu/armv7/sunxi is actually armv7 specific, while most of it is just generic code that could as well be used on an AArch64 SoC. Move all files that are not really tied to armv7 into a new mach-sunxi directory.
