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:
https://docs.turris.cz/hw/turris-1x/turris-1x/
https://project.turris.cz/en/hardware.html
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. ]
