i2c: sun8i_rsb: Initialize chips in .child_pre_probe

Chips attached to the RSB bus require an initialization command before
they can be used. (Specifically, this command programs the chip's
runtime address.) The driver does this in its .probe_chip hook, under
the assumption that .probe_chip is called during child probe. This is
not the case; .probe_chip is only called by dm_i2c_probe, which is
intended for use by board-level code, not for chips with OF nodes.

Since this initialization command must be run before a child chip can be
used, do it before probing each child.

tools: mkimage: Add Allwinner TOC0 support

Most Allwinner sunxi SoCs have separate boot ROMs in non-secure and

existing sunxi_egon image type. The secure boot ROM (SBROM) uses a
completely different image type, known as TOC0.

A TOC0 image is composed of a header and two or more items. One item
is the firmware binary. The others form a chain linking the firmware
signature to the root-of-trust public key (ROTPK), which has its hash
burned in the SoC's eFuses. Signatures are made using RSA-2048 + SHA256.

The pseudo-ASN.1 structure is manually assembled; this is done to work
around bugs/quirks in the boot ROM, which vary between SoCs. This TOC0
implementation has been verified to work with the A50, A64, H5, H6,

sunxi: pinctrl: Implement pin muxing functions

Implement the operations to get pin and function names, and to set the
mux for a pin. The pin count and pin names are calculated as if each
bank has the maximum number of pins. Function names are simply the index
into a list of { function name, mux value } pairs.

We assume all pins associated with a function use the same mux value for
that function. This is generally true within a group of pins on a single
port, but generally false when some peripheral can be muxed to multiple
ports. For example, A64 UART3 uses mux 3 on port D, and mux 2 on port H.
But all of the port D pins use the same mux value, and so do all of the
port H pins. This applies even when the pins for some function are not
contiguous, and when the lower-numbered mux values are unused. A good
example of both of these cases is SPI0 on most SoCs.

This strategy saves a lot of space (which is especially important for
SPL), but where the mux value for a certain function differs across
ports, it forces us to choose a single port for that function at build
time. Since almost all boards use the default (i.e. reference design)
pin muxes[1], this is unlikely to be a problem.

Commit f11513d99787 ("net: phy: realtek: Add tx/rx delay config for

to set up the proper delay scheme for the RX and TX lines. A similar
change in the kernel revealed that those properties were mostly wrong.
The kernel DTs got updated over the last few months, but we were missing
out on the U-Boot version.

Just sync in the phy-mode properties from the mainline kernel,
v5.17-rc7, to avoid the breaking DT sync that late in the cycle.

This fixes Ethernet operation on the affected boards.

sunxi: Fix old GMAC pinmux setup

Commit 5bc4cd05d7d4 ("sunxi: move non-essential code out of s_init()")
moved the call to eth_init_board() from s_init() into board_init_f().
This means it's now only called from the SPL, which makes sense for
most of the other moved low-level functions. However the GMAC pinmux and
clock setup in eth_init_board() was not happy about that, so it broke

Since Ethernet is of no use in the SPL anyway, just move the call into
board_init(), which is only run in U-Boot proper.

This fixes Ethernet operation for the A20 SoCs, which broke in

was set to 50000000 and after it is 104000000.

Rename DT node 'spi-flash@0 in armada-3720-espressobin-u-boot.dtsi to
'flash@0' and set custom U-Boot 'spi-max-frequency' back to 50000000.
