4fcc084eeb power: twl4030: Add twl4030_i2c_read() function
Function twl4030_i2c_read() is like twl4030_i2c_read_u8() but instead of
single value it rather returns array of values.

a3e458524c cros_ec: Handling EC_CMD_GET_NEXT_EVENT
With commit 6900797678 ("cros_ec: Support keyboard scanning with
EC_CMD_GET_NEXT_EVENT") check_for_keys() tries to read keyboard
strokes using EC_CMD_GET_NEXT_EVENT. But the sandbox driver does
not understand this command. We need to reply with
-EC_RES_INVALID_COMMAND to force check_for_keys() to fall back to
use EC_CMD_MKBP_STATE. Currently the driver prints

    ** Unknown EC command 0x67

in this case. With the patch the message is suppressed.

In a future patch we should upgrade the sandbox driver to provide
EC_CMD_GET_NEXT_EVENT support.

there and rk_lvds.c has no counterpart, so keep them as is.

eb89025013 rockchip: rk3399: Init clocks in U-Boot proper if SPL was not run
It's possible to chainload U-Boot proper from the vendor firmware in
rk3399 chromebooks, but the way the vendor firmware sets up clocks is
somehow different than what U-Boot expects. This causes the display to
stay devoid of content even though vidconsole claims to work (with
patches in process of being upstreamed).

This is meant to be a rk3399 version of commit d3cb46aa8c ("rockchip:
Init clocks again when chain-loading") which can detect the discrepancy,
but this patch instead checks whether SPL (and therefore the clock init)
was run via the handoff functionality and runs the init if it was not.

Amlogic SM1 SoCs doesn't work over 50MHz. When phase sets to 270', it's
working fine over 50MHz on Amlogic SM1 SoCs.
Since Other Amlogic SoCs doens't report an issue, phase value is using
to 180' by default.

To distinguish which value is used adds an u-boot only sm1 compatible.

In future, it needs to find what value is a proper about each SoCs.

b055a05b98 input: add support for FN1 - FN10 on crosswire kbd
Chromebooks and the sandbox use a crosswire keyboard with function keys
FN1 - FN10. These keys are needed when running UEFI applications like GRUB
or the UEFI SCT.

Add support for these keys when translating from key codes to
ECMA-48 (or withdrawn ANSI 3.64) escape sequences.

All escape sequences start with 0x1b. So we should not repeat this
byte in the kbd_to_ansi364 table.

For testing use:

sandbox_defconfig + CONFIG_EFI_SELFTEST=y

$ ./u-boot -D -l

=> setenv efi_selftest extended text input
=> bootefi selftest

3a8ee3df83 board: Rename uclass to sysinfo
This uclass is intended to provide a way to obtain information about a
U-Boot board. But the concept of a U-Boot 'board' is the whole system,
not just one circuit board, meaning that 'board' is something of a
misnomer for this uclass.

In addition, the name 'board' is a bit overused in U-Boot and we want to
use the same uclass to provide SMBIOS information.

The obvious name is 'system' but that is so vague as to be meaningless.
Use 'sysinfo' instead, since this uclass is aimed at providing information
on the system.

Rename everything accordingly.

Note: Due to the patch delta caused by the symbol renames, this patch
shows some renamed files as being deleted in one place and created in
another.

6900797678 cros_ec: Support keyboard scanning with EC_CMD_GET_NEXT_EVENT
The cros_ec_keyb driver currently uses EC_CMD_MKBP_STATE to scan the
keyboard, but this host command was superseded by EC_CMD_GET_NEXT_EVENT
and unavailable on more recent devices (including gru-kevin), as it was
removed in cros-ec commit 87a071941b89 ("mkbp: Add support for buttons
and switches.") dated 2016-07-06.

The EC_CMD_GET_NEXT_EVENT has been available since cros-ec commit
d1ed75815efe ("MKBP event signalling implementation") dated 2014-10-20,
but it looks like it isn't included in firmware-* branches for at least
link, nyan-big, samus, snow, spring, panther and peach-pit which have
defconfigs in U-Boot. So this patch falls back to the old method if the
EC doesn't recognize the newer command.

The implementation is mostly adapted from Depthcharge commit
f88af26b44fc ("cros_ec: Change keyboard scanning method.").

On a gru-kevin, the current driver before this patch fails to read the
pressed keys with:

    out: cmd=0x60: 03 9d 60 00 00 00 00 00
    in-header: 03 fc 01 00 00 00 00 00
    in-data:
    ec_command_inptr: len=-1, din=0000000000000000
    check_for_keys: keyboard scan failed

However the keyboard works fine with the newer command:

    out: cmd=0x67: 03 96 67 00 00 00 00 00
    in-header: 03 ef 00 00 0e 00 00 00
    in-data: 00 00 00 00 00 00 00 00 00 00 00 00 00 00
    ec_command_inptr: len=14, din=00000000f412df30
    key_matrix_decode: num_keys = 0
      0 valid keycodes found
    out: cmd=0x67: 03 96 67 00 00 00 00 00

    in-data: 00 00 00 00 00 00 00 00 00 00 00 00 10 00

329dccc067 sandbox: implement reset
Up to now the sandbox would shutdown upon a cold reset request. Instead it
should be reset.

In our coding we use static variables like LIST_HEAD(efi_obj_list). A reset
can occur at any time, e.g. via an UEFI binary calling the reset service.
The only safe way to return to an initial state is to relaunch the U-Boot
binary.

The reset implementation uses execv() to relaunch U-Boot.

fb71c3f490 rtc: initialize emulated RTC from environment variable
Up to now the emulated RTC is initialized using the U-Boot build time.

With this patch the environment variable 'rtc_emul_epoch' can be used to
provide a better initial time. The variable is a decimal string with
the number of seconds since 1970-01-01. Here is an example where the RTC
had not been probed yet:

    => setenv rtc_emul_epoch 1610109000
    => date
    Date: 2021-01-08 (Friday)    Time: 12:30:00

If the variable does not exist, the U-Boot build time is used as fallback.

The environment variable may be set when shutting down the operating system
if the U-Boot environment is exposed to the OS (cf. ENV_IS_IN_FAT and
ENV_IS_IN_EXT4).

8a38abfc43 dm: Use driver_info index instead of pointer
At present we use a 'node' pointer in the of-platadata phandle_n_arg
structs. This is a pointer to the struct driver_info for a particular
device, and we can use it to obtain the struct udevice pointer itself.

Since we don't know the struct udevice pointer until it is allocated in
memory, we have to fix up the phandle_n_arg.node at runtime. This is
annoying since it requires that SPL's data is writable and adds a small
amount of extra (generated) code in the dm_populate_phandle_data()
function.

Now that we can find a driver_info by its index, it is easier to put the
index in the phandle_n_arg structures.

Update dtoc to do this, add a new device_get_by_driver_info_idx() to look
up a device by drive_info index and update the tests to match.

Based on Linux kernel commit fc256f5789cb ("mtd: nand: pxa3xx: enable
NAND controller if the SoC needs it"). This commit adds support for the
Armada 8040 nand controller.

The kernel commit says this:

    Marvell recent SoCs like A7k/A8k do not boot with NAND flash
    controller activated by default. Enabling the controller is a matter
    of writing in a system controller register that may also be used for
    other NAND related choices.

7a49a16ec5 Revert "mmc: zynq: parse dt when probing"
This reverts commit 942b5fc032.

This is partial revert of the above commit.

mmc_of_parse() is reading no-1-8-v from device tree and if set,
it is clearing the UHS speed capabilities of cfg->host_caps.
cfg->host_caps &= ~(UHS_CAPS | MMC_MODE_HS200 |
		    MMC_MODE_HS400 | MMC_MODE_HS400_ES);

This is still missing to clear UHS speeds like SDHCI_SUPPORT_SDR104,
SDHCI_SUPPORT_SDR50 and SDHCI_SUPPORT_DDR50.

Even if we clear the flags SDHCI_SUPPORT_XXX in mmc_of_parse(),
these speed flags are getting set again in cfg->host_caps in
sdhci_setup_cfg().

The reason for this is, SDHCI_SUPPORT_XXX flags are cleared
only if controller is not capable of supporting MMC_VDD_165_195 volts.

if (caps & SDHCI_CAN_VDD_180)
	cfg->voltages |= MMC_VDD_165_195;

if (!(cfg->voltages & MMC_VDD_165_195))
	caps_1 &= ~(SDHCI_SUPPORT_SDR104 | SDHCI_SUPPORT_SDR50 |
		    SDHCI_SUPPORT_DDR50);

It means "no-1-8-v", which is read from DT is not coming in to effect.
So it is better we keep the host quirks(SDHCI_QUIRK_NO_1_8_V) to
clear UHS speeds based on no-1-8-v from device tree.

Hence revert the functionality related to no-1-8-v only, rest is fine
in the patch.

4f0278dac5 net: sun8i-emac: Lower MDIO frequency
When sending a command via the MDIO bus, the Designware MAC expects some
bits in the CMD register to describe the clock divider value between
the main clock and the MDIO clock.
So far we were omitting these bits, resulting in setting "00", which
means "/ 16", so ending up with an MDIO frequency of either 18.75 or
12.5 MHz.
All the internal PHYs in the H3/H5/H6 SoCs as well as the Gbit Realtek
PHYs seem to be fine with that - although it looks like to be severly
overclocked (the MDIO spec limits the frequency to 2.5 MHz).
However the external 100Mbit PHY on the Pine64 (non-plus) board is
not happy with that, Ethernet was actually never working there, as the
PHY didn't probe.

As we set the EMAC clock (via AHB2) to 300 MHz in ATF (on the 64-bit
SoCs), and use 200 MHz on the H3, we need the highest divider of 128
to let the MDIO clock end up below the required 2.5 MHz.

This enables Ethernet on the Pine64(non-plus).

88ae8fba84 net: sun8i-emac: Make internal PHY handling more robust
The current implementation of sun8i_get_ephy_nodes() makes quite some
assumptions, in general relying on DT path names is a bad idea.
I think the idea of the code was to determine if we are using the
internal PHY, for which there are simpler and more robust methods:

Rewrite (and rename) the existing function to simply lookup the DT node
that "phy-handle" points to, using the device's DT node.
Then check whether the parent of that PHY node is using an "H3 internal
MDIO" compatible string. If we ever get another internal MDIO bus
implementation, we will probably need code adjustments anyway, so this
is good enough for now.

7edcb4e288 net: sun8i_emac: Simplify and fix error handling for RX
The error handling in recv() is somewhat broken, for instance
good_packet isn't really used, and it's hardly readable. Also we try
to check for short or too big packets, but those are actually filtered
out by the hardware.

Simplify the whole routine and improve the error handling:
- Bail out early if the current RX descriptor is not ready.
- Enable propagation of runt, huge and broken packets.
- Check for runt and huge packets, and return 0 to indicate this.
  This will force the framework to call free_pkt for cleanup.
- Avoid aligning the packet buffer for invalidation again.

When initialising the TX DMA descriptors, we mostly chain them up,

That means they are still invalid, and the OWN bit should NOT be set

In fact when we later tell the MAC about the beginning of the chain,
and enable TX DMA in the start() routine, the MAC will start fetching
TX descriptors prematurely, as it can be seen by dumping the TX_DMA_STA
