04d4ec9c57 pinctrl: at91: add option to use drive strength bits
SAM9X60 uses high and low drive strengths. To implement this, in
at91_pinctrl_mux_ops::set_drivestrength we need bit numbers of
drive strengths (1 for low, 2 for high), thus change the code to
allow the usage of drive strength bit numbers.

a71e2f933b arm: at91: Add gardena-gateway-at91sam support
The GARDENA smart Gateway boards are equipped with an Atmel / Microchip
AT91SAM9G25 SoC and with 128 MiB of RAM and 256 MiB of NAND storage.
This patch adds support for this board including SPL support. Therefore
the AT91Boostrap is not needed on this platform any more.

9ea6f718eb Makefile: Add Kconfig option CONFIG_SPL_IMAGE to select the SPL binary
This patch adds the CONFIG_SPL_IMAGE option to select the SPL image that
shall be used to generate the combined SPL + U-Boot image. The default
value is the current value "spl/u-boot-spl.bin".

This patch also sets CONFIG_SPL_IMAGE to "spl/boot.bin" for AT91 targets
which use SPL NAND support (boot from NAND). For these build targets the
combined image "u-boot-with-spl.bin" is now automatically generated and
can be programmed into NAND as one single image (vs. SPL image and U-Boot
as 2 separate images).

6c04bd3857 watchdog: at91sam9_wdt: Fix WDT setup in at91_wdt_start()
This patch fixes the timer register setup in at91_wdt_start() to
correctly configure the register again. The input timeout value is
now in milli-seconds instead of seconds with the new watchdog API.
Make sure to take this into account and only use a max timeout
value of 16 seconds as appropriate for this SoC.

Also the check against a lower timeout value than 0 is removed. This
check makes no sense, as the timeout value is unsigned.

7fbd42f5af watchdog: Handle SPL build with watchdog disabled
This patch adds some checks, so that the watchdog can be enabled in main
U-Boot proper but can be disabled in SPL.

This will be used by some AT91SAM based boards, which might enable the
watchdog in the main U-Boot proper and not in SPL. It will be enabled in
SPL by default there, so no need to configure it there. This approach
saves some space in SPL.

e567dfb213 serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL
This patch adds an alterative SPL version of atmel_serial_enable_clk().
This enables the usage of this driver without full clock support (in
drivers and DT nodes). This saves some space in the SPL image.

Please note that this fixed clock support is only added to the SPL code
in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL
should not be affected.

This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART
input clock. It defaults to 132096000 for ARCH_AT91 but can be set to
a different value if needed.

Please note that this call might also be needed for non SPL_OF_CONTROL

call because its binary grows too big. So I disabled it for these kind
of targets for now.

7dee1848d7 ARM: at91: sama5d2: Wrap cpu detection to fix macb driver
When introducing the SAMA5D27 SoCs, the SAMA5D2 series got an additional
chip id. The check if the cpu is sama5d2 was changed from a preprocessor
definition (inlining a call to 'get_chip_id()') to a C function,
probably to not call get_chip_id twice?

That however broke a check in the macb ethernet driver. That driver is
more generic and also used for other platforms. I suppose this solution
was implemented to use it in 'gem_is_gigabit_capable()', without having
to stricly depend on the at91 platform:

	#ifndef cpu_is_sama5d2
	#define cpu_is_sama5d2() 0
	#endif

That only works as long as cpu_is_sama5d2 is a preprocessor definition.
(The same is still true for sama5d4 by the way.) So this is a straight
forward fix for the workaround.

The not working check on the SAMA5D2 CPU lead to an issue on a custom
board with a LAN8720A ethernet phy connected to the SoC:

	=> dhcp
	ethernet@f8008000: PHY present at 1
	ethernet@f8008000: Starting autonegotiation...
	ethernet@f8008000: Autonegotiation complete
	ethernet@f8008000: link up, 1000Mbps full-duplex (lpa: 0xffff)
	BOOTP broadcast 1
	BOOTP broadcast 2
	BOOTP broadcast 3
	BOOTP broadcast 4
	BOOTP broadcast 5
	BOOTP broadcast 6
	BOOTP broadcast 7
	BOOTP broadcast 8
	BOOTP broadcast 9
	BOOTP broadcast 10
	BOOTP broadcast 11
	BOOTP broadcast 12
	BOOTP broadcast 13
	BOOTP broadcast 14
	BOOTP broadcast 15
	BOOTP broadcast 16
	BOOTP broadcast 17

	Retry time exceeded; starting again

Notice the wrong reported link speed, although both SoC and phy only
support 100 MBit/s!

The real issue on reliably detecting the features of that cadence
ethernet mac IP block, is probably more complicated, though.

85c3d46322 arm: sunxi: Enable DM_MMC on required SoCs
Enabling DM_MMC is forcing CONFIG_BLK=y so if any board which uses
SCSI must need to enable DM_SCSI otherwise SCSI reads on that particular
target making invalid reading to the disk drive.

Allwinner platform do support SCSI on A10, A20 and R40 SoC's out of
these only A10 have DM_SCSI enabled. So enabling DM_MMC on A20, R40
would eventually end-up with scsi disk read failures like [1]

So, enable DM_MMC in all places of respective SoC's instead of enabling
them globally to Allwinner platform.

Now, DM_MMC is enabled in Allwinner SoC's except A20 and R40.

ccd063e981 watchdog: Move watchdog_dev to data section (BSS may not be cleared)
This patch moves all instances of static "watchdog_dev" declarations to
the "data" section. This may be needed, as the BSS may not be cleared
in the early U-Boot phase, where watchdog_reset() is already beeing
called. This may result in incorrect pointer access, as the check to
"!watchdog_dev" in watchdog_reset() may not be true and the function
may continue to run.

After building ATF it is needed to copy the generated bl31.bin file to
the U-Boot source tree.

Make this step explicit in the instructions.

00102ae520 pico-imx7d: README: Recommend the usage of a USB hub
Since commit 9e3c0174da ("pico-imx7d: Add LCD support") we started to
notice some hangs in U-Boot.

There is not an issue on such commit per se, but due to the LCD support
the current drawn is increased and this may cause issues when powering
pico-imx7d-pi from USB.

Some computers may be a bit strict with USB current draw and will
shut down their ports if the draw is too high.

The solution for that is to use an externally powered USB hub between the
board and the host computer.

Add such recommendation to the README file.

40ee163cc4 configs: icorem6: Use imx6 cratch register for bootcount
SRAM address used for bootcount on exiting code is erasing
previous count value when system reset from Linux. So use
the dedicated imx6 scratch register, GPR2 to preserve the
contents even if the system reset from Linux.

8b9cba0295 configs: icore: Fix U-Boot proper loading from nand
SPL on Engicam i.Core M6 boards enabled DM, so it would require some
malloc() pool before relocation in order to load U-Boot proper properly.

So, enable SPL malloc() pool of 0x2000 size similarly like what we have
used for icore mmc defconfigs.

b7de88cd5c ARM: imx6q_logic: Enable UUID support
With UUID support, the root can now point to UUID.  This makes
swiching between mmc 0 and mmc 1 easier by simplying changing
mmcdev between 0 and 1.  From there, the scripts handle the rest.

9b8d9ec41a pico-imx6ul: Fix eMMC boot after DM_MMC conversion
After the DM_MMC conversion the following eMMC boot error is observed:

U-Boot SPL 2019.04-rc4 (Mar 20 2019 - 18:53:28 +0000)
Trying to boot from MMC1
MMC Device 0 not found
spl: could not find mmc device 0. error: -19
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

This happens because the SPL code does not initialize the SDHC pins
and clock.

Fix it by moving the original eMMC initialization from U-Boot proper
to SPL.
