board: ti: common: board_detect: Fix EEPROM read quirk for 2-byte
EEPROM detection logic in ti_i2c_eeprom_get() involves figuring out
whether addressing is 1-byte or 2-byte. There are currently different
behaviours seen across boards as documented in commit bf6376642fe8
("board: ti: common: board_detect: Fix EEPROM read quirk"). Adding to
the list, we see that there are 2-byte EEPROMs that read properly
with 1-byte addressing with no offset.
For ti_i2c_eeprom_am6_get where eeprom parse operation is dynamic, the
earlier commit d2ab2a2bafd5 ("board: ti: common: board_detect: Fix
EEPROM read quirk for AM6 style data") tried to resolve this by running
ti_i2c_eeprom_get() twice. However this commit along with its former
commit fails on J7 platforms where EEPROM successfully return back the
header on 1-byte addressing and continues to do so until an offset is
introduced. So the second read incorrectly determines the EEPROM as
1-byte addressing.
A more generic solution is introduced here to solve
this issue: 1-byte read without offset and 1-byte read with offset. If
both passes, it follows 1-byte addressing else we proceed with 2-byte
addressing check.

serial: Use -EAGAIN in getc and putc
U-Boot serial code already handles -EAGAIN value from getc and putc
callbacks. So change drivers code to return -EAGAIN when HW is busy instead
of doing its own busy loop and waiting until HW is ready.

arm: uniphier: use DM_TIMER of arm a9 global timer
All uniphier v7 SoCs have cortex-a9 and use cortex-a9 global timer
in a simple implementation. Now DM_TIMER of it is available
on 35751c7f3f ("timer: sti: convert sti-timer to arm a9 global timer"),
so let's switch to it.
The old driver reads the lower 32bits of counter field
and sets the prescaler as 50 with PERIPHCLK(=50MHz),
so the global timer works as a 32-bit 1MHz timer.
The DM_TIMER uses the whole 64bits with no prescaler,
so the global timer works as a 64-bit PERIPHCLK timer.
CONFIG_SYS_HZ_CLOCK is set as the default PERIPHCLK frequency,
if there is no 'clocks' property in devicetree.

pinctrl: uniphier: add check if pins are valid
The pinctrl datas of uniphier SoCs are the minimal subsets of kernel's one,
and some tables has no data to save the footprint size.
If the board dts tries to match a pin name on no pins defined SoC,
the footprint magic code causes "Synchronous Abort".
This checks if the 'pins' data is valid,
and if empty, avoids the abort with the warning as follows:

cmd: source: Support specifying config name
As discussed previously [1,2], the source command is not safe to use with
verified boot unless there is a key with required = "images" (which has its
own problems). This is because if such a key is absent, signatures are
verified but not required. It is assumed that configuration nodes will
provide the signature. Because the source command does not use
configurations to determine the image to source, effectively no
verification takes place.
To address this, allow specifying configuration nodes. We use the same
syntax as the bootm command (helpfully provided for us by fit_parse_conf).
By default, we first try the default config and then the default image. To
force using a config, # must be present in the command (e.g. `source
$loadaddr#my-conf`). For convenience, the config may be omitted, just like
the address may be (e.g. `source \#`). This also works for images
(`source :` behaves exactly like `source` currently does).

treewide: Use NULL for script image name
Two callers of image_source_script specify an image name. However, both
use the deprecated @ syntax, indicating that they have not been updated
in a while. If CONFIG_FIT_SIGNATURE is enabled, we will reject such
names outright. Back in commit 152576a598c ("stm32mp: stm32prog: handle
U-Boot script in flashlayout alternate"), we even renamed one of the
nodes. Instead of hard-coding a script image name, just use the default
image.
