Revert "arm: bootm: Disable LMB reservation for command line and board info on arm64"

2021-08-08T15:59:01+00:00

This reverts commit 2359fa7a87848626bcbd3399e92c657595880cd7. While the goal is valid and there is surely unused memory in that area, we also have a lot of crucial things still located at the top-of-memory while running lmb_alloc_base. Such things are the page table (tlb_addr), relocated U-Boot and the active stack. Possibly more. So this patch was premature, we will need relocations of those things first if we want to use the range. Fixes booting on the IOT2050, but likely also on other boards. It got stuck on relocating the FDT - over the relocated U-Boot code. Signed-off-by: Jan Kiszka

global: Convert simple_strtoul() with hex to hextoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 16 in each call. Add a new hextoul() function and update the code to use it. Add a proper comment to simple_strtoul() while we are here. Signed-off-by: Simon Glass

arm: bootm: Disable LMB reservation for command line and board info on arm64

2021-07-09T16:15:41+00:00

On arm64, board info is not applicable and kernel command line patched into the DT, so the LMB reservation here makes no sense anymore. On legacy arm32, this might still be necessary on systems which do not use DT or use legacy ATAGS. Disable this LMB reservation on arm64. This also permits Linux DT to specify reserved memory node at address close to the end of DRAM bank, i.e. overlaping with U-Boot location. Since after boot, U-Boot will be no more, this is OK.

arm64: Fix relocation of env_addr if POSITION_INDEPENDENT=y

2021-06-28T18:47:10+00:00

If both POSITION_INDEPENDENT and SYS_RELOC_GD_ENV_ADDR are enabled, wherever original env is placed anywhere, it should be relocated to the right address. Relocation offset gd->reloc_off is calculated with SYS_TEXT_BASE in setup_reloc() and env address gd->env_addr is relocated by the offset in initr_reloc_global_data(). gd->env_addr = (orig env) + gd->reloc_off = (orig env) + (gd->relocaddr - SYS_TEXT_BASE) However, SYS_TEXT_BASE isn't always runtime base address when POSITION_INDEPENDENT is enabled. So the relocated env_addr might point to wrong address. For example, if SYS_TEXT_BASE is zero, gd->env_addr is out of memory location and memory exception will occur. There is a difference between linked address such as SYS_TEXT_BASE and runtime base address. In _main, the difference is calculated as "run-vs-link" offset. The env_addr should also be added to the offset to fix the address. gd->env_addr = (orig env) + ("run-vs-link" offset) + gd->reloc_off = (orig env) + (SYS_TEXT_BASE - _start) + (gd->relocaddr - SYS_TEXT_BASE) = (orig env) + (gd->relocaddr - _start) Cc: Marek Vasut Signed-off-by: Kunihiko Hayashi Acked-by: Marek Vasut Tested-by: Marek Vasut

2021-05-24T18:21:30+00:00

This commit does the same thing as Linux commit 33def8498fdd. Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

arm: zimage: Use correct symbol to hide messages in SPL

2021-04-27T12:05:30+00:00

When zImage support was added to SPL, the messages were hidden to reduce code size. However, the wrong config symbol was used. Since this file is only built when CONFIG_SPL_FRAMEWORK=y, the messages were always hidden. Use the correct symbol so the messages are printed in U-Boot proper. Also use IS_ENABLED to drop the #ifdef. Fixes: 431889d6ad9a ("spl: zImage support in Falcon mode") Signed-off-by: Samuel Holland

arm64: gic-v3-its: Clear the Pending table before enabling LPIs

2021-04-20T11:31:12+00:00

The GICv3 RM requires "The first 1KB of memory for the LPI Pending tables must contain only zeros on initial allocation, and this must be visible to the Redistributors, or else the effect is UNPREDICTABLE". And as the following statement, we here clear the whole Pending tables instead of the first 1KB. "An LPI Pending table that contains only zeros, including in the first 1KB, indicates that there are no pending LPIs. The first 1KB of the LPI Pending table is IMPLEMENTATION DEFINED. However, if the first 1KB of the LPI Pending table and the rest of the table contain only zeros, this must indicate that there are no pending LPIs." And there isn't any pending LPI under U-Boot, so it's unnecessary to load the contents of the Pending table during the enablement, then set the GICR_PENDBASER.PTZ flag.
