The axp223 appears to be the same as the axp221, except that it uses the
rsb to communicate rather then the p2wi. At least all the registers we use
are 100% the same.

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.

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.

It turns out that there is a too large spread between boards to handle this
with a default value, turn this into Kconfig options, and set the values
the factory images are using for the Colombus and Mele_M9 boards.
Note this changes the ZQ default when not overriden through defconfig from
120 to 123, as that is what most boards seem to actually use.

Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors") mx25pdk
hangs like this:
CPU: Freescale i.MX25 rev1.2 at 399 MHz
Reset cause: WDOG
Board: MX25PDK
I2C: ready
DRAM: 64 MiB
(hangs)
Add a specific relocate_vectors macro that skips the vector relocation, as the
i.MX25 SoC does not provide RAM at the high vectors address (0xFFFF0000), and
(0x00000000) maps to ROM.
This allows mx25 to boot again.

The low-level debugging functions are useful to debug the early boot
stage where the full UART driver is not available.
UniPhier SoCs need to initialize the UART port 0 to use this feature.
The initialization routine is called at the very entry of the

The max size of available memories on slot0 and slot1 is 32MB because
- EA[25] signal is not output on the save-pin mode which is

- EA[25] signal is not connected by the limitation (or bug?) of

On OMAP platforms (like OMAP5) Linux kernel fails to detect a SATA
device if it is used by U-Boot.
It happens because U-Boot does not reset SATA controller before boot.
Reset the controller on OS boot so that Linux will have a clean state
to work with.

Commit 8bc347e2ec17 "ARM: bootm: Allow booting in secure mode on hyp capable
systems" added the capability to select nonsec vs sec mode boot via an
environment var.
There is a subtle gotcha with this functionality, which is that the PSCI nodes
are still created in the fdt (via armv7_update_dt->fdt_psci) even when booting
in secure mode. Which means that if the kernel is PSCI aware then it will fail
to boot because it will try and do PSCI from secure world, which won't work.
This likely didn't get noticed before because the original purpose was to
support booting the legacy linux-sunxi kernels which don't understand PSCI.
To fix expose boot_nonsec (renaming with armv7_ prefix) outside of bootm.c and
use from the virt-dt code.
As well as avoiding the creation of the PSCI nodes we should also avoid
reserving the secure RAM, so do so.

This controller was introduced on Tegra114 to handle XUSB pads. On
Tegra124 it is also used for PCIe and SATA pin muxing and PHY control.
Only the Tegra124 PCIe and SATA functionality is currently implemented,
with weak symbols on Tegra114.
Tegra20 and Tegra30 also provide weak symbols for these functions so
that drivers can use the same API irrespective of which SoC they're
being built for.

This reset is required for PCIe and the corresponding ID therefore needs
to be defined. The enumeration value for this was properly defined on
some SoCs but not on others. Similarly, some contained it in the mapping
of peripheral IDs to clock IDs, other didn't. This patch defines it
consistently for all supported SoC generations.

The current current watchdog timeout of 12 seconds is a bit small for
booting into Linux, especially when using a NFS based rootfs. So lets
change this timeout to a more defensive value of 30 seconds.
Also we now call the hw_watchdog_init() function so that we override
the value already configured from the Preloader.

Nyan-big is a Tegra124 clamshell board that is very similar to venice2, but
it has a different panel, the sdcard cd and wp sense are flipped, and it has
a different revision of the AS3722 PMIC.
This is the Acer Chromebook 13 CB5-311-T7NN (13.3-inch HD, NVIDIA
Tegra K1, 2GB). The display is not currently supported, so it should
boot on other nyan-based Chromebooks also, but only the device tree for
nyan-big is provided here.
The device tree file is from Linux but with features removed which are
unlikely to be supported in U-Boot soon (regulators, pinmux). Also the
addresses are updated to 32-bit.
