turris_1x: Normalize Kconfig usage

use defconfigs, select in some cases on the target itself, or update the

Merge patch series "Add Turris 1.x board"
Marek Mojík <marek.mojik@nic.cz> says:
Hello all,
this is a continuation of previous work by Pali to add support for the
Turris 1.x board. As the patches were based on u-boot v2022.04, a
nontrivial rebasing was needed.
Some notes:
- Some options that are in SD defconfig are disabled in NOR defconfig
because over the years u-boot grew and the old NOR defconfig will not
fit into NOR memory.
- SD boot with RAM larger than 2GB will only allocate 2GB of RAM (We
were not able to fix this yet)

powerpc: Add support for CZ.NIC Turris 1.x routers
Add support for CZ.NIC Turris 1.x routers.
CZ.NIC Turris 1.0 (RTRS01) and 1.1 (RTRS02) are open source routers, they
have dual-core PowerPC Freescale P2020 CPU and are based on reference
Freescale P2020RDB-PC-A board design.
Hardware design is fully open source, all firmware and hardware design
files are available at Turris project website:
The P2020 BootROM can load U-Boot either from NOR flash or from SD card.
We add the new defconfigs, turris_1x_nor_defconfig, which configures
U-Boot for building the NOR image, and turris_1x_sdcard_defconfig, which
configures U-Boot for building an image suitable for SD card.
The defconfig for NOR image is stripped-down a - many config options
enabled in SD defconfig are disabled for NOR defconfig. This is because
U-Boot grew non-trivially in the last two years and it would not fit
into the space allocated for U-Boot in the NOR memory. In the future we
may try to use LTO to reduce the size of the code and enable more
options.
The design of CZ.NIC Turris 1.x routers is based on Freescale P2020RDB-PC-A
board, so some code from boards/freescale/p1_p2_rdb_pc is used and linked
into Turris 1.x board code.
Turris 1.x code in this patch uses modern distroboot and can boot Linux
kernel from various locations, including NAND, SD card, USB flash disks,
NVMe disks or SATA disks (connected to extra SATA/SCSI PCIe controllers).
Via distroboot is implemented also rescue NOR boot for factory recovery,
triggered by reset button, like on other existing Turris routers.
SD boot with RAM larger than 2GB will only allocate 2GB of RAM (We were
not able to fix this yet)
[ Because various CONFIG_ macros were migrated to Kconfig since the last
time this worked on upstream U-Boot (in 2022), a non-trivial rebasing
was needed and some issues were solved. ]

board_f: Add support for CONFIG_OF_BOARD_FIXUP for XIP images

gd->fdt_blob before relocation points to read-only flash memory.
So U-Boot calls board_fix_fdt() with read-only gd->fdt_blob pointer which

Fix this issue by introducing a new config option OF_INITIAL_DTB_READONLY

ddr: marvell: a38x: Import old DDR training code from 2017 version of U-Boot
Import DDR training code from commit 1b69ce2fc0ec ("arm: mvebu:
ddr3_debug: remove self assignments") into
drivers/ddr/marvell/a38x/old/. The code is not used yet.
Explanation:
Since 2019, on some Turris Omnia boards we have been having problems
with newer versions of Marvell's DDR3 training code for Armada 38x,
which is ported from mv-ddr-marvell [1] to U-Boot into the
drivers/ddr/marvell/a38x/ directory:
- sometimes the DDR3 training fails on some older boards, sometime it
fails on some newer boards
- other times it succeeds, but some boards experience crashes of the
operating system after running for some time.
Using the stock version of Turris Omnia's U-Boot from solved these
issues, but this solution was not satisfactory, since we wanted
features from new U-Boot.
Back in 2020-2022 we have spent several months trying to debug the
issues, working with Marvell, on our own, and also with U-Boot
community, but these issues persist still.
One solution we used back in 2019 was a "hybrid U-Boot": the SPL part
(containing the DDR3 training code) was taken from the stock version,
while the proper part was current U-Boot at the time. This solution also
has its drawbacks, of which the main one is the need to glue binaries
from two separate builds.
Since then there have been some more changes to the DDR3 training code
in upstream mv-ddr-marvell that have been ported to U-Boot. We have
provided our users experimental builds of U-Boot in the TurrisOS so that
they could try upgrading the firmware and let us know if those problems
still exist. And they do.
We do not have the time nor manpower to debug this problem and fix it
properly. Marvell was also no able to provide a solution to this,
probably because they do not have the manpower as well.
I have therefore come up with this "not that pretty" solution: take the
DDR3 training code from an older version of U-Boot that is known to
work, put it into current U-Boot under old/ subdirectory within
drivers/ddr/marvell/a38x/, build into the SPL binary both the old and
new versions and make it possible to select the old version via an env
variable.

For board revisions where the WAN ethernet PHY reset GPIO is controllable
via MCU we currently insert a phy-reset-gpios property into the ethernet
controller node. The mvneta driver parses this property and uses the
GPIO to reset the PHY.
But this phy-reset-gpios property is not a valid DT binding in upstream
kernel. Instead, a reset-gpios property should be inserted into the
ethernet PHY node. This correct DT binding is supported by the DM ETH PHY
U-Boot driver.
Insert the reset-gpios property into the WAN PHY node instead the
phy-reset-gpios property in WAN ETH node so that Linux will correctly use
the reset GPIO.
Enable the CONFIG_DM_ETH_PHY config option so that U-Boot will also use
the correct DT property.
Note: currently there are 4 ethernet controller drivers parsing the
wrong DT property: dwc_eth_qos, fex_mxc, mvneta and mvpp2. We should
convert all relevant device-trees to use reset-gpios so that we can get
rid of these drivers parsing this property.
