ppc: lmb: move arch specific lmb reservations to arch_misc_init()

2024-09-03T20:08:50Z

All the current function definitions of arch_lmb_reserve() are doing the same thing -- reserve the U-Boot memory region. The powerpc(ppc) architecture, in addition, is making some LMB reservations for the bootm related image loading. Move these ppc specific reservations to the arch_misc_init() function. This allows to move the U-Boot memory region reservation to a different function, and remove arch_lmb_reserve() in a subsequent commit. Signed-off-by: Sughosh Ganu Reviewed-by: Simon Glass

lmb: make LMB memory map persistent and global

2024-09-03T20:08:50Z

The current LMB API's for allocating and reserving memory use a per-caller based memory view. Memory allocated by a caller can then be overwritten by another caller. Make these allocations and reservations persistent using the alloced list data structure. Two alloced lists are declared -- one for the available(free) memory, and one for the used memory. Once full, the list can then be extended at runtime.

global_data: Move pci_clk to m68k and powerpc

Only m68k and powerpc use this field, so move it to the arch-specific info, to reduce the size for other archs. Signed-off-by: Simon Glass

turris_1x: Normalize Kconfig usage

2024-07-13T16:42:15Z

We don't set many options in the board Kconfig entry file but instead use defconfigs, select in some cases on the target itself, or update the "default" options of the main entries when needed. In this case we can remove most of the board Kconfig entries and just add them to the defconfig like other platforms. Signed-off-by: Tom Rini

Merge patch series "Add Turris 1.x board"

2024-07-12T20:00:45Z

Marek Mojík 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

2024-07-12T19:07:43Z

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. ] Signed-off-by: Pali Rohár Signed-off-by: Marek Mojík Reviewed-by: Marek Behún

powerpc: mpc85xx: use CONFIG_VAL() for SYS_MONITOR_BASE in start.s

powerpc: mpc8xxx: Extend find_law() to find_law_by_addr_id()

2024-07-12T19:07:43Z

The find_law() function searches for LAW just by physical address. This is unsuitable for cases with overlapping LAWs. Extend it to find_law_by_addr_id(), which searches for LAW by physical address and target id. Add a static inline definition of the original find_law() into fsl_law.h header.
