According to the HW team, for some reason the normal clock select code
picks what appears to be a perfectly valid 375KHz SD card clock, based
on the CAR clock source and SDMMC1 controller register settings (CAR =
408MHz PLLP0 divided by 68 for 6MHz, then a SD Clock Control register
divisor of 16 = 375KHz). But the resulting SD card clock, as measured by
the HW team, is 700KHz, which is out-of-spec. So the WAR is to use the
values given in the TRM PLLP table to generate a 400KHz SD-clock (CAR
clock of 24.7MHz, SD Clock Control divisor of 62) only for SDMMC1 on
T210 when the requested clock is <= 400KHz. Note that as far as I can
tell, the other requests for clocks in the Tegra MMC driver result in
valid SD clocks.

As per the T210 TRM, when running at 3.3v, the SDMMC1 tap/trim and
autocal values need to be set to condition the signals correctly before
talking to the SD-card. This is the same as what's being done in CBoot,
but it gets reset when the SDMMC1 HW is soft-reset during SD driver
init, so needs to be repeated here. Also set autocal and tap/trim for
SDMMC3, although no T210 boards use it for SD-card at this time.

VOP display endpoint pipeline configuration differs
between rk3288 vs rk3399.
These VOP pipeline configuration depends on how the
different display interfaces connected in sequence to
IN and OUT ports like for,
RK3288:
vopb_out: port {
#address-cells = <1>;
#size-cells = <0>;
vopb_out_edp: endpoint@0 {
reg = <0>;
remote-endpoint = <&edp_in_vopb>;
};
vopb_out_hdmi: endpoint@1 {
reg = <1>;
remote-endpoint = <&hdmi_in_vopb>;
};
vopb_out_lvds: endpoint@2 {
reg = <2>;
remote-endpoint = <&lvds_in_vopb>;
};
vopb_out_mipi: endpoint@3 {
reg = <3>;
remote-endpoint = <&mipi_in_vopb>;
};
};
RK3399:
vopb_out: port {
#address-cells = <1>;
#size-cells = <0>;
vopb_out_edp: endpoint@0 {
reg = <0>;
remote-endpoint = <&edp_in_vopb>;
};
vopb_out_mipi: endpoint@1 {
reg = <1>;
remote-endpoint = <&mipi_in_vopb>;
};
vopb_out_hdmi: endpoint@2 {
reg = <2>;
remote-endpoint = <&hdmi_in_vopb>;
};
vopb_out_mipi1: endpoint@3 {
reg = <3>;
remote-endpoint = <&mipi1_in_vopb>;
};
vopb_out_dp: endpoint@4 {
reg = <4>;
remote-endpoint = <&dp_in_vopb>;
};
};
here, HDMI interface has endpoint 1 in rk3288 and 2 in rk3399.
The rockchip vop driver often depends on this determined endpoint
number and stored in vop_mode. So based on this vop_mode the bpp
and pin polarity would configure on detected display interface.
Since, the existing driver using rk3288 vop mode settings enabling
the same will result wrong display interface configuration for rk3399.
Add the patch for fixing these vop modes for rk3399.

The implementation of dma_map_single() and dma_unmap_single() is
exactly the same for all the architectures that support them.
Factor them out to <linux/dma-mapping.h>, and make all drivers to
include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>.
If we need to differentiate them for some architectures, we can
move the generic definitions to <asm-generic/dma-mapping.h>.
Add some comments to the helpers. The concept is quite similar to
the DMA-API of Linux kernel. Drivers are agnostic about what is
going on behind the scene. Just call dma_map_single() before the
DMA, and dma_unmap_single() after it.

The NovaThor U8500 SoC was released by ST-Ericsson in 2011.
It was used for some development boards like the CALAO Systems
Snowball SBC, but mass production was primarily for Android
smartphones like the Samsung Galaxy S III mini.
Previous support for U8500 was removed in
commit 68282f55b8 ("arm: Remove unused ST-Ericsson u8500 arch")
since none of the boards were converted to generic boards
before the deadline.
The new code does not have much in common with the previous code.
I have completely rewritten everything, embracing the Driver Model
and device trees wherever possible.
The U8500 support is a bit more minimal for now - my primary
use case is to use U-Boot as alternative bootloader for some of the
U8500 Samsung smartphones. At the moment U-Boot is chain-loaded from
the original Samsung bootloader. A side effect of this is that we
can (temporarily) get away without implementing some functionality
- e.g. all clocks are already enabled by the original bootloader.
More functionality will be added in future patches.

Currently imx-specific bootaux command doesn't support ELF format
firmware for Cortex-M4 core.
This patches introduces a PoC implementation of handling elf firmware
(load_elf_image_phdr() was copy-pasted from elf.c just for PoC).
ELF64 binaries isn't supported yet.
This has the advantage that the user does not need to know to which
address the binary has been linked to. However, in order to handle
and load the elf sections to the right address, we need to translate the
Cortex-M4 core memory addresses to primary/host CPU memory
addresses (Cortex A7/A9 cores).
This allows to boot firmwares from any location with just using
bootaux, e.g.:
> tftp ${loadaddr} hello_world.elf && bootaux ${loadaddr}
Similar translation table can be found in the Linux remoteproc
driver [1].

Add the sdram driver for PX30 to support ddr3, ddr4, lpddr2 and lpddr3.
For TPL_BUILD, the driver implement full dram init and without DM
support due to the limit of internal SRAM size.
For SPL and U-Boot proper, it's a simple driver with dm for get
dram_info like other SoCs.

Since we have new DRAM type and to support different DRAM size in different
CS, we need more bits, so introduce sys_reg3 to record the info.
Note that the info in sys_reg3 is extension to sys_reg2 and the info in
sys_reg2 is the same as before. We define the DRAM_INFO with sys_reg3 as
VERSION2.
All the ENC macro are moved to sdram_common.h since the sdram.c only
need to do the info decode.

imx6_is_bmode_from_gpr9 always returns false, because
IMX6_SRC_GPR10_BMODE is 1<<28 and gets casted to u8 on return.
This moves the function body into imx6_src_get_boot_mode, since that is the

The Allwinner H6 SoC has a register to set the PIO banks' voltage. When
it mismatches the real voltage supplied to the VCC to the PIO supply,
the PIO will work improperly.
The PIO controller also has a register that contains the status of each
VCC rail of the PIO supplies, and it has the same definition with the
configuration register. so we can just copy the content of this register
to the configuration register at startup, to ensure the configuration is
correct at startup stage.

Half DQ configuration seems to be very rare for H6 based boards/STBs,
but exists nevertheless. Currently the only known product which needs

This commit adds support for half DQ configuration. Code was tested
for regressions on other configurations (OrangePi 3 1 GiB/LPDDR3, Tanix
TX6 4 GiB/DDR3) and none were found.
Thanks to Icenowy Zheng for help with this code.
