The board supports up to 8 GiB memory. The memory is soldered on the
board but the configuration is equivalent to a dual chip select, dual
rank DIMM module.

With a 8GiB memory board, it seems that the "very unlikely event" of a
DDR initialization with non-optimal values are not really that unlikely.
It happens in about every other reboot. As described in erratum
A-009942, preset the DEBUG_28 register with an optimal value. The value
iself depends on the memory configuration of the board, but the used
value seems to work well for all variants.

A board might need to get the source of the RCW word, which is also the
boot source in most cases.
These defines are taken from the LS1028A and I expect they are the same
across the SoCs with the same chassis, after all, there was already a
reset source for NOR flash.

Code for changing boot source is platform generic and can be used by any
P1* and P2* compatible RDB board. Not only by boards which use config
header file p1_p2_rdb_pc.h.
So move this code from p1_p2_rdb_pc.h to p1_p2_bootsrc.h and cleanup macros
for generating boot source env variables in CONFIG_EXTRA_ENV_SETTINGS.
This allows to use code for resetting board and rebooting to other boot
source also by other boards in future.

Currently default fallback SDHC mode is 1-bit. Add new config option
CONFIG_SYS_FSL_ESDHC_DEFAULT_BUS_WIDTH to allow specifying default fallback
mode. This is useful e.g. for SPL builds which loads other parts from SD
card during boot process.

8-bit mode is not supported by SD cards and on P2020 are four SDHC pins
shared with SPI (so if P2020 board have also SPI then only 4-bit SDHC mode
is provided). So 8-bit SDHC mode is really bad default.
When max bus width is not provided then set mode to 1-bit. This mode is
supported by all cards, so it is the best option for fallback mode.
Also P2020 bootrom sets mode to 1-bit when booting from SD/MMC card.

Header file asm/fsl_law.h already provides correct definition for second
and third PCIe controller (LAW_TRGT_IF_PCIE_2 and LAW_TRGT_IF_PCIE_3). But
is missing definition for the first PCIe controller (LAW_TRGT_IF_PCIE_1).
Note that existing definition for LAW_TRGT_IF_PCIE_2 and LAW_TRGT_IF_PCIE_3
are slightly complicated, but are really correct for P2020 platform.

These frequency calculations depend on the RCW format, which is not
dependent on any particular board. Switch to using ARCH symbols instead
of TARGET.
This whole function could probably use less ifdefs, but for now just do
a minimal conversion.

This adds an SFP binding for the processors it is present on. I have
only tested this for the LS1046A.
Signed-off-by: Sean Anderson <sean.anderson@seco.com>
QorIQ platforms now use different clock bindings. Although we don't use
the device tree for clocks on this platform, it is helpful to sync it
because then the bindings will more closely match Linux. Additionally,
it allows for using more clock fractions (such as platform/4).
This corresponds to Linux commit b6f5e7019391 ("ARM: dts: ls1021a:
update the clockgen node").

This adds a driver for the Security Fuse Processor (SFP) present on
LS1012A, LS1021A, LS1043A, and LS1046A processors. It holds the
Super-Root Key (SRK), One-Time-Programmable Master Key (OTPMK), and
other "security" related fuses. Similar devices (sharing the same name)
are present on other processors, but for the moment this just supports
the LS2 variants.
The mirror registers are loaded during power-on reset. All mirror
registers must be programmed or read at once. Because of this, `fuse
prog` will program all fuses, even though only one might be specified.
To prevent accidentally burning through all your fuse programming cycles
with something like `fuse prog 0 0 A B C D`, we limit ourselves to one
programming cycle per reset. Fuses are numbered based on their address.
The fuse at 0x1e80200 is 0, the fuse at 0x1e80204 is 1, etc.
The TA_PROG_SFP supply must be enabled when programming fuses, but must
be disabled when reading them. Typically this supply is enabled by
inserting a jumper or by setting a register in the board's FPGA. I've
also added support for using a regulator. This could be helpful for
automatically issuing the FPGA write, or for toggling a GPIO controlling
the supply.
I suggest using the following procedure for programming:
1. Override the fuses you wish to program
=> fuse override 0 2 A B C D
2. Inspect the values and ensure that they are what you expect
=> fuse sense 0 2 4
3. Enable TA_PROG_SFP
4. Issue a program command using OSPR0 as a dummy. Since it contains the
write-protect bit you will usually want to write it last anyway.
=> fuse prog 0 0 0
5. Disable TA_PROG_SFP
6. Read back the fuses and ensure they are correct
=> fuse read 0 2 4

If CONFIG_VIDEO_DM=n we query the display size from the serial console.
Especially when using a remote console the response can be so late that
it interferes with autoboot.
Only query the console size when running an EFI binary.
Add debug output showing the determined console size.

When the UEFI sub-system is initialized it sends an escape sequence to the
serial console to determine the terminal size. This stops the
run_command_list() function of the console emulation from recognizing the
U-Boot command line prompt.
Add a 'print -e' command as first command in the command list to work
around this issue.

Depending on backup register value, U-Boot SPL maintains the debug unit
powered-on for debugging purpose; only BUCK1 is required for powering
the debug unit, so revert the setting for all the other power lanes,
except BUCK3 that has to be always on.
To be functional this patch requires a modification in the debugger
,openocd for example, to update the STM32MP15 backup register when it is
required to debug SPL after reset. After deeper analysis this behavior
will be never supported in tools so the associated code, will be never
used and the associated code can be removed.
