7b7ad5c31c rockchip: video: Add a video-output driver
Some rockchip SoCs include video output (VOP). Add a driver to support this.
It can output via a display driver (UCLASS_DISPLAY) and currently HDMI and
eDP are supported.

c253948341 rockchip: video: Add a display driver for rockchip HDMI
Some Rockchip SoCs support HDMI output. Add a display driver for this so
that these displays can be used on supported boards.

Unfortunately this driver is not fully functional. It cannot reliably read
EDID information over HDMI. This seems to be due to the clocks being
incorrect - the I2C bus speed appears to be up to 100x slower than the
clock settings indicate. The root cause may be in the clock logic.

It also adds the ability to reset the SCTRL register at the very beginning

1222305b55 arm: lpc32xx: switch SPL builds to driver model
For NXP LPC32xx boards the change enables SPL_DM option, this allows
to use any driver model UART driver in SPL images, hence a restriction
on HSUART in SPL image is removed and well as definitions for non-DM
NS16550 driver, its DM version is used instead.

Because SPL_DM requires malloc(), enable CONFIG_SPL_SYS_MALLOC_SIMPLE
for LPC32xx boards.

The change adds about 5KB to the resulting SPL image (for devkit3250
board SPL image is increased from 10672 to 15608 bytes).

d25ba89e8b arm: lpc32xx: switch serial console to driver model
On NXP LPC32xx platform for non-SPL builds the change adds
standard (NS16550) and high-speed UARTs to driver model.
Due to specific of DM NS16550 device description UART clock can not be
got in runtime and by default it is set to 13MHz, if board PERIPH_CLK
is different, this should be specified in board configuration file.

For SPL builds HSUARTs are disabled and non-DM NS16550 driver is
compiled, if needed.

The change also updates default configs of devkit3250 and work_92105
boards to reflect updates in platform files.

For some board designs, it might be useful to switch the DC-DC

for EMI reasons.

For this, override the mxs_power_setup_dcdc_clocksource function

Example:
void mxs_power_setup_dcdc_clocksource(void)
{
    mxs_power_switch_dcdc_clocksource(POWER_MISC_FREQSEL_20MHZ);

c107c0c05c armv8: fsl-layerscape: Make DDR non secure in MMU tables
DDR has been set as secure in MMU tables. Non-secure master such
as SDHC DMA cannot access data correctly. Mixing secure and non-
secure MMU entries requirs the MMU tables themselves in secure
memory. This patch moves MMU tables into a secure DDR area.

Early MMU tables are changed to set DDR as non-secure. A new
table is added into final MMU tables so secure memory can have
2MB granuality.

gd->secure_ram tracks the location of this secure memory. For
ARMv8 SoCs, the RAM base is not zero and RAM is divided into several
banks. gd->secure_ram needs to be maintained before using. This
maintenance is board-specific, depending on the SoC and memory
bank of the secure memory falls into.

2b714cfad4 arm: ls1021a: Ensure LS1021 ARM Generic Timer CompareValue Set 64-bit
This patch addresses a problem mentioned recently on this mailing list:
[1].

In that posting a LS1021 based system was locking up at about 5 minutes
after boot, but the problem was mysteriously related to the toolchain
used for building u-boot.  Debugging the problem reveals a stuck
interrupt 29 on the GIC.

It appears Freescale's LS1021 support in u-boot erroneously sets the
64-bit ARM generic PL1 physical time CompareValue register to all-ones
with a 32-bit value.  This causes the timer compare to fire 344 seconds
after u-boot configures it.  Depending on how fast u-boot gets the
kernel booted, this amounts to about 5-minutes of Linux uptime before
locking up.

Apparently the bug is masked by some toolchains.  Perhaps this is
explained by default compiler options, word sizes, or binutils versions.
At any rate this patch makes the manipulation explicitly 64-bit which
alleviates the issue.

52d093112a sunxi: clock: Set AHB1 clock frequency to 200MHz on Allwinner H3
The 3.4 kernel from the Allwinner SDK is clocking AHB1 at 200MHz
on Allwinner H3 and using PLL6 as the clock source (PLL6/3).
This can be verified by reading the value of the AHB1_APB1_CFG_REG
register via /dev/mem. It always reads as 0x3180 regardless of
the current cpufreq operating point. So this configuration should
be safe for use in U-Boot too.

PLL6 also needs to be configured before it is used as the clock
source, according to the "CCU / Programming Guidelines" section
of the Allwinner manual.

The current low AHB1 clock speed is limiting the USB transfer
speed when booting via FEL. This patch can increase the FEL USB
transfer speed from ~510 KB/s to ~950 KB/s.

36afd45136 spl: change return values of spl_*_load_image()
Make spl_*_load_image() functions return a value instead of
hanging if a problem is encountered. This enables main spl code
to make the decision whether to hang or not, thus preparing
it to support alternative boot devices.

Some boot devices (namely nand and spi) do not hang on error.
Instead, they return normally and SPL proceeds to boot the
contents of the load address. This is considered a bug and
is rectified by hanging on error for these devices as well.

a3c252d6d6 video: mxsfb: introduce lcdif_power_down
Introudce a new function lcdif_power_down.

1. Waits for a VSYNC interrupt to guarantee the reset is done at the
   VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?)
   and helps the LCDIF work normally at the kernel stage.
2. Add power down function to stop lcdif.

The reason to introduce lcdif_power_down is that we want lcdif to be in
initial state when doing uboot reset or before kernel boot to make
system stable, otherwise system may hang.

Existing driver gets the actual omap hammc base address + 0x100
bytes as the first 0x100 bytes is not used by the driver. But
with DM conversion the base address from DT is different, to
accommodate the offset adding res0[0x100] to struct hsmmc.

8d8e13e129 arm: socfpga: enable data/inst prefetch and shared override in the L2
Update the L2 AUX CTRL settings for the SoCFPGA.

Enabling D and I prefetch bits helps improve SDRAM performance on the
platform.

Also, we need to enable bit 22 of the L2. By not having bit 22 set in the
PL310 Auxiliary Control register (shared attribute override enable) has the
side effect of transforming Normal Shared Non-cacheable reads into Cacheable
no-allocate reads.

Coherent DMA buffers in Linux always have a Cacheable alias via the
kernel linear mapping and the processor can speculatively load cache
lines into the PL310 controller. With bit 22 cleared, Non-cacheable
reads would unexpectedly hit such cache lines leading to buffer
corruption.

af654d1461 sunxi: retrieve FEL-provided values to environment variables
This patch extends the misc_init_r() function on sunxi boards
to test for the presence of a suitable "sunxi" SPL header. If
found, and the loader ("fel" utility) provided a non-zero value
for the boot.scr address, then the corresponding environment
variable fel_scriptaddr gets set.

misc_init_r() also sets (or clears) the "fel_booted" variable depending
on the active boot device, using the same logic as spl_boot_device().

The goal is to provide sufficient information (within the U-Boot
environment) to make intelligent decisions on how to continue the boot
process, allowing specific customizations for the "FEL boot" case.

a188438175 sunxi: (mksunxiboot) signature to indicate "sunxi" SPL variant
This patch follows up on a discussion of ways to improve support
for the sunxi FEL ("USB boot") mechanism, especially with regard
to boot scripts, see:
https://groups.google.com/d/msg/linux-sunxi/wBEGUoLNRro/rHGq6nSYCQAJ

The idea is to convert the (currently unused) "pad" bytes in the
SPL header into an area where data can be passed to U-Boot. To
do this safely, we have to make sure that we're actually using
our "sunxi" flavor of the SPL, and not the Allwinner boot0.

The modified mksunxiboot introduces a special signature to the
SPL header in place of the "pub_head_size" field. This can be
used to reliably distinguish between compatible versions of sunxi
SPL and anything else (older variants or Allwinner's boot0).

89983478bd gpio: lpc32xx: fix issues with port3 gpio
The current simplify lpc32xx gpio driver implementation assume a
maximum of 32 GPIO per port; there are a total of 22 GPI, 24 GPO
and 6 GPIO to managed on port 3.

Update the driver to fix the following:
1) When requesting GPI_xx and GPO_xx on port 3 (xx is the same number)
   the second call to "gpio_request" will return -EBUSY.

2) The status of GPO_xx pin report the status of the
   corresponding GPI_xx pin when using the "gpio status" command.

3) The gpio driver may setup the direction register for the wrong
   gpio when calling "gpio_direction_input" (GPI_xx) or
   "gpio_direction_output" (GPO_xx) on port 3; the call to the
   direction is require to use the "gpio status" command.

The following change were done in the driver:
1) port3 GPI are cache in a separate 32 bits in the array.
2) port3 direction register written only for GPIO pins.
3) port3 GPO & GPIO (as output) are read using "p3_outp_state".
4) LPC32XX_GPI_P3_GRP updated to match the change.

37cf215253 imx: vf610 add get_cpu_rev
Since we need to support runtime check for different drivers, we need
to add get_cpu_rev for vf610, otherwise there will be build errors.

This patch introduces a dummy CPU id which is not read from chip
silicon. Later when we can get the real id from chip, can fix the
value of MXC_CPU_VF610 then.

7296a02358 mxc: ocotp fix hole in shadow registers
There is a hole in shadow registers address map of size 0x100
between bank 5 and bank 6 on iMX6QP, iMX6DQ, iMX6SDL, iMX6SX and iMX6UL.
Bank 5 ends at 0x6F0 and Bank 6 starts at 0x800. When reading the fuses,
we should account for this hole in address space.

Similar hole exists between bank 14 and bank 15 of size
0x80 on iMX6QP, iMX6DQ, iMX6SDL and iMX6SX.
Note: iMX6SL has only 0-7 banks and there is no hole.
Note: iMX6UL doesn't have this one.

When reading, we use register offset, so need to account for holes
to get the correct address.
When writing, we use bank/word index, there is no need to account
for holes, always use bank/word index from fuse map.

The new reimplemented function mx6_dram_cfg only invokes mx6_ddr3_cfg
when ddr_type is for DDR3. Later we can use ddr_type to initialize
MMDC for LPDDR2.

Initialize ddr_type for different boards which enable SPL.

For ex. If eSDHC/qDMA/eDMA are unused and with disabled status in dts,
User can enable CONFIG_FSL_DEVICE_DISABLE and set "devdis:esdhc,qdma,edma"
in hwconfig, thus ESDHC controller & eDMA/qDMA will be clock gated to

DP83865 ethernet phy used on DRA74x-evm is quirky and the datasheet
provided IODELAY values for standard RGMII phys do not work.

Silicon Revision(SR) 2.0 provides an alternative bit configuration
that allows us to do a "gross adjustment" to launch the data off a
different internal clock edge. Manual IO Delay overrides are still
necessary to fine tune the clock-to-data delays. This is a necessary
workaround for the quirky ethernet Phy we have on the platform.

NOTE: SMA registers are spare "kitchen sink" registers that does
contain bits for other workaround as necessary as well. Hence the
control for the same is introduced in a generic SoC specific, board
generic location.

This patch moves pxa to the common timer functions added in commit

  8dfafdd - Introduce common timer functions <Rob Herring>

The (removed) pxa timer code (specifically __udelay()) could deadlock at
the 32-bit boundary of get_ticks().  get_ticks() returned a 32-bit value
cast up to a 64-bit value.  If get_ticks() + tmo in __udelay() crossed
the 32-bit boundary, the while condition became unconditionally true and
locked the processor.  Rather than patch the specific pxa issues, simply
move everything over to the common code.

327f0d23c8 lpc32xx: move common SLC NAND defines to arch/config.h
A number of LPC32xx SLC NAND defines is dictated by controller
hardware limits and OOB layout is defined by operating system, the
definitions are common for all users. Since those macro are used
in out of NAND SLC driver code (simple NAND SPL framework), they can
not be placed into the driver, therefore move them from board config
files to arch/config.h

The change also adds OOB layout details specific to small page NAND
devices taken from Linux kernel.
