2018-07-31sunxi: add basic memory map definitions of H6 SoCIcenowy Zheng
The Allwinner H6 SoC come with a totally new memory map. Add basical definition of the new memory map into a header file, and let the cpu.h header include it in the situation of H6.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-04-20sunxi: Use H3/A64 DRAM initialization code for R40Chen-Yu Tsai
The R40 seems to have a variant of the memory controller found in the H3 and A64 SoCs. Adapt the code for use on the R40. The changes are based on released DRAM code and comparing register dumps from boot0. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2017-04-05sunxi: DRAM: add Allwinner H5 supportAndre Przywara
The DRAM controller in the Allwinner H5 SoC is again very similar to the one in the H3 and A64. Based on the existing socid parameter, add support for this controller by reusing the bulk of the code and only deviating where needed. These new bits set or cleared here and there have been mostly found by looking at DRAM register dumps after using the H5 boot0 and comparing them to what we set in the code. So for now it's mostly unclear what those bits actually mean - hence the missing names and comments. Also add the delay line parameters taken from the boot0 and libdram disassembly. Register setup differences between H5 and H3 are courtesy of Jens Kuske. Signed-off-by: Andre Przywara <andre.przywara@arm.com> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2017-01-04sunxi: A64: use H3 DRAM initialization code for A64 as wellJens Kuske
The A64 DRAM controller is very similar to the H3 one, so the code can be reused with some small changes. This refactoring does not change the code size for the existing H3 part.

2015-01-22sun9i: Add cpu_sun9i.h with iomem definesHans de Goede

2015-01-22sunxi: Rename cpu.h to cpu_sun4i.hHans de Goede
sun4i - sun8i have (aprox.) the same iomem layout, but sun9i is quite different, so add a wrapper cpu.h which includes the right mach specific cpu_sun#i.h based on mach, like we already do with clock.h and dram.h .

2015-01-14sunxi: Move usb-controller init code out of ehci-sunxi.c for reuse for otgHans de Goede
Most of the usb-controller init code found in ehci-sunxi.c also is necessary to init the otg usb controller, so move it to a common place. While at it also update various #ifdefs / defines for sun8i support. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
2015-01-14sunxi: Add support for the rsb (Reduced Serial Bus)Hans de Goede
sun8i (A23) introduces a new bus for communicating with the pmic, the rsb, the rsb is also used to communicate with the pmic on the A80, and is documented in the A80 user manual. This commit adds support for this based on the rsb driver from the allwinner u-boot sources. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

2015-01-14sunxi: Add sunxi_get_sid helper functionHans de Goede
On sun6i the SID is stored in the pmic, rather then in the SoC itself, add a helper function to abstract this away. This makes our MAC address generation code also work on sun6i. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
