e35feb99ab efi_selftest: Add geometric shapes character selftest
Draw symbols from Unicode's "Geometric shapes" page which translate to
code page 437 code points 1-31. These are used by UEFI applications to
draw user interfaces using EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL.
The output has to be checked manually on the screen for correctness.

33b2899811 efi_selftest: Add box drawing character selftest
UEFI applications rely on Unicode output capability, and might use that
for drawing pseudo-graphical interfaces using Unicode defined box
drawing characters.

Add a simple test to display the most basic box characters, which would
need to be checked manually on the screen for correctness.

4dd134c0c7 efi_selftest: Add international characters test
UEFI relies entirely on unicode output, which actual fonts displayed on
the screen might not be ready for.

Add a test displaying some international characters, to reveal missing
glyphs, especially in our builtin fonts.
This would be needed to be manually checked on the screen for

5ea38f95c4 video: console: Parse UTF-8 character sequences
efi_console / UEFI applications (grub2, sd-boot, ...) pass UTF-8
character sequences to vidconsole which results in wrong glyphs for code
points outside of ASCII. The truetype console expects Unicode code
points and bitmap font based consoles expect code page 437 code points.
To support both convert UTF-8 to UTF-32 and pass Unicode code points in
vidconsole_ops.putc_xy(). These can be used directly in console_truetype
and after conversion to code page 437 in console_{normal,rotate}.

This fixes rendering of international, symbol and box drawing characters
used by UEFI applications.

95167db37c arm: Check FEAT_CCIDX when parsing ccsidr_el1 register
Current Cache Size ID Register (ccsidr_el1) has two "flavors"
depending on whether FEAT_CCIDX is implemented or not.
When FEAT_CCIDX is implemented Associativity parameter
is coded on bits [23:3] and NumSets parameter on bits [55:32].
When FEAT_CCIDX is not implemented then Associativity parameter
is coded on bits [12:3] and NumSets parameter on bits [27:13].
Current U-Boot code does not check whether FEAT_CCIDX is implemented
and always parses ccsidr_el1 as if FEAT_CCIDX was not implemented.
This is of course wrong on systems where FEAT_CCIDX is implemented.
This patch fixes that problems and tests whether FEAT_CCIDX
is implemented or not and accordingly parses the ccsidr_el1 register.

c6a13f3d6f arm64: gic: Add power up sequence for GIC-600
Arm's GIC-600 features a Power Register (GICR_PWRR),
which needs to be programmed to enable redistributor
operation. Power on the redistributor and  wait until
the power on state is reflected by checking the bit
GICR_PWRR.RDPD == 0. While running U-Boot in EL3
without enabling this register, GICR_WAKER.ChildrenAsleep
bit is not getting cleared and loops infinitely.
This register(GICR_PWRR) must be programmed to mark the frame
as powered on, before accessing other registers in the frame.
Rest of initialization sequence remains the same.

ARM GIC-600 IP complies with ARM GICv3 architecture.
Enable this config if GIC-600 IP present.

e6ea13eba9 arm: mach-k3: Fix config check for FS_LOADER
load_firmware() API calls fs-loader APIs and checks for CONFIG_FS_LOADER
before calling those APIs. The if check only checks for CONFIG_FS_LOADER
but not for CONFIG_SPL_FS_LOADER.

When CONFIG_FS_LOADER is enabled, load_firmware() API calls fs-loader APIs
but this is done at SPL stage and at this time FS_LOADER is not built yet
as a result we see below build error.

12bc1a5462 rockchip: boot_mode: fix rockchip_dnl_key_pressed requiring ADC support
ADC support is implied by the Rockchip arch Kconfig but that means it
should be possible to disable ADC support and still be able to build.

However the weak implementation of rockchip_dnl_key_pressed() currently
blindly use functions from the ADC subsystem which do not exist when ADC
is not enabled, failing the build.

Therefore, let's encapsulate this logic with a check on the ADC symbol
being selected.

768636c371 rockchip: jaguar-rk3588: enable SARADC and derivatives
The SARADC is used on Jaguar for multiple things:
- channel 0 is used (at runtime) as a BIOS button,
- channel 2 is exposed on the Mezzanine connector for customer specific
  logic,
- channel 5 and 6 are used for identification,

Since the SARADC requires a vref-supply provided by the RK806 PMIC, its
support and the support for its regulators are also enabled.

The button, adc, pmic and regulator commands are also enabled for CLI
use in U-Boot for debugging and scripting purposes.

The RK806 PMIC on Jaguar being routed on the SPI bus, let's enable
Rockchip SPI controller driver.

Finally, the SARADC channel 1 on Jaguar is hardwired so will never
change in the lifetime of a unit, for that reason, disable the Rockchip
Download Mode check by setting ROCKCHIP_BOOT_MODE_REG symbol to 0.

This adds support for the SARADCv2 found on RK3588.

There is no stop callback as it is currently configured in single
conversion mode, where the ADC is powered down after a single conversion

Due to what seems to be a silicon bug, a controller reset needs to be
issued before starting a channel conversion otherwise Rockchip says that
channel 1 will error whatever that means. This is aligned with upstream
and downstream Linux kernel as well as downstream U-Boot.

f172575d92 power: rk8xx: add support for RK806
This adds support for RK806, only the SPI variant has been tested.

The communication "protocol" over SPI is the following:
 - write three bytes:
   - 1 byte: [0:3] length of the payload, [6] Enable CRC, [7] Write
   - 1 byte: LSB register address
   - 1 byte: MSB register address
 - write/read length of payload

The CRC is always disabled for now.

The RK806 technically supports I2C as well, and this should be able to
support it without any change, but it wasn't tested.

The DT node name prefix for the buck converters has changed in the
Device Tree and is now dcdc-reg. The logic for buck converters is
however manageable within the current logic inside the rk8xx regulator
driver. The same cannot be said for the NLDO and PLDO.

Because pmic_bind_children() parses the DT nodes and extracts the LDO
index from the DT node name, NLDO and PLDO will have overlapping
indices. Therefore, we need a separate logic from the already-existing
ldo callbacks. Let's reuse as much as possible though.

f047e4ab97 regulator: rk8xx: add indirection level for some ldo callbacks
By passing a rk8xx_reg_info directly to the internal get_value, it'd be
possible to call this same function with a logic for getting the
rk8xx_reg_info different from the current get_ldo_reg, e.g. for NLDO and
PLDO support for RK806.

No logic change is expected.

d771597fbb regulator: rk8xx: fix SWITCH enable on RK809
On RK809 in PMIC_POWER_ENX registers, in order to set or clear a bit N,
the bit at offset N + 4 needs to be set otherwise nothing is done.

This fixes the inability to modify the SWITCH state on RK809.

811323ffd4 regulator: rk8xx: remove unused functions
Those two functions had their last user removed in commit f9c68a566c
("rockchip: phycore_rk3288: remove phycore_init() function") part of
v2023.01 release, so let's do some cleanup here.
