https://source.denx.de/u-boot/custodians/u-boot-tpm into next Up to now we configure the entire memory space for U-Boot as RWX. For modern architectures and security requirements, it's better to map the memory properly. This pull request adds basics support for mapping the U-Boot binary with proper (RO, RW, RW^X) memory permissions on aarch64 right after we relocate U-Boot in the top of DRAM. It's worrth noting that the linker script annotations are only added for the aarch64 architecture. We can, in the future, try to unify the linker -- at least for the architectures that have enough in common and expand this

2024-12-30powerpc: Introduce and enforce assembler checks on GPR usageJ. Neuschäfer
PowerPC general-purpose registers are historically specified as plain numbers (0-31), which makes them hard to distinguish from immediates. For this reason, include/ppc_asm.tmpl defines aliases named r0-r31. This can still lead to uncaught mistakes if a register is used in place of a number. Instead of (e.g.) 5 use %r5, which will result in an assembler warning if used as a number. Turn these warnings into errors by passing `--fatal-warnings` to the assembler. I verified with gazerbeam_defconfig (MPC83xx) and qemu-ppce500_defconfig (MPC85xx) that this patch results in the same machine code. Signed-off-by: J. Neuschäfer <[email protected]>
2024-12-30powerpc: Fix 0 vs. r0 confusion in X/D-form instructionsJ. Neuschäfer
Instructions such as dcbi are in the X-form; they have RA and RB fields and the effective address (EA) is computed as (RA|0)+(RB). In words, this means that if RA is zero, the left-hand side of the addition is zero, otherwise the corresponding GPR is used. r0 can never be used on the left-hand side of a X-form instruction. For D-form instructions such as addis, the Power ISA illustrates this in the instruction pseudo-code: if RA = 0 then RT <- EXTS(SI || 0x0000) else RT <- (RA) + EXIS(SI || 0x0000) In all of these cases, RA=0 indicates the value zero, not register r0. I verified with gazerbeam_defconfig (MPC83xx) and qemu-ppce500_defconfig (MPC85xx) that this patch results in the same machine code. Signed-off-by: J. Neuschäfer <[email protected]>

2024-09-03lmb: do away with arch_lmb_reserve()Sughosh Ganu
All of the current definitions of arch_lmb_reserve() are doing the same thing -- reserve the region of memory occupied by U-Boot, starting from the current stack address to the ram_top. Introduce a function lmb_reserve_uboot_region() which does this, and do away with the arch_lmb_reserve() function. Instead of using the current value of stack pointer for starting the reserved region, have a fixed value, considering the stack size config value.

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.

2024-07-12Merge patch series "Add Turris 1.x board"Tom Rini
Marek Mojík <[email protected]> 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)
2024-07-12powerpc: Add support for CZ.NIC Turris 1.x routersPali Rohár
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 <[email protected]> Signed-off-by: Marek Mojík <[email protected]> Reviewed-by: Marek Behún <[email protected]>

Nothing in-tree calls watchdog_reset() anymore (that stopped two years ago with the removal of the WATCHDOG_RESET macro). So that function is dead code. That was the only caller of reset_85xx_watchdog(), so that can obviously also be removed. Finally, init_85xx_watchdog() is/was also not called from anywhere, so that can go away as well, which nicely also removes a bit of arch-specific code from the generic watchdog.h header.
