* MIPS: fix optimised memset returning garbageDenis Orlov2022-03-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a subtle bug in arch/mips/lib/memset.S, used if option MIPS_OPTIMIZED_STRING_FUNCTIONS is enabled, which results in not writing the correct return value into v0 register if the value to fill memory with is 0. The bug stems from a missing '.set noreorder' directive before the first beqz instruction. This results in an assembler stuffing a 'nop' instruction in the beqz delay slot instead of an instruction writing the return value into v0 register that was supposed to go there. That leads to an error that appears when reading memory from SPI Flash and that was mentioned here: http://lists.infradead.org/pipermail/barebox/2021-June/036557.html There are a few ways of fixing this bug. The directive '.set noreorder' that shows up a bit later in code could be moved up and placed right before the memset label (as it was originally in Linux codebase - see a583158c9ce822c96a718fbf877cec1e5f9ad75d). Or, rather, the move and the branch instruction could be swapped, thus allowing the assembler to properly place move in delay slot (as it is done in Linux now - see 68dec269ee29c3abfd09596fbee7e40d875a6ab3) - that is what is done in this patch.

* clk: composite: fix possible NULL pointer dereferenceAhmad Fatoum2022-03-081-3/+7
| | | | | | | | | | | A composite clock is at most composed of a mux, a divider and a gate, but it may lack one or two of these components. In that case, a NULL pointer is passed, so we need to deal with this case.

* scripts: bareboximd: Fix -c optionSascha Hauer2022-02-282-5/+11
| | | | | | | | | | | | | | | | | Using mmap in read_file doesn't work when the same file is written afterwards with write_file. This problem was fixed in 738601e125 ("scripts/common: fix write_file when opened with mmap"). Using mmap in read_file was removed in 07b87a0908 ("scripts/common: Do not mmap in read_file_2()") but then re-introduced for bareboximd in 013e8ea757 ("scripts: bareboximd: Use mmap when possible"). I'll put my brown paper bag on for this :( This patch fixes the issue by explicitly avoiding mmap when the file is written later as done with the -c option to bareboximd Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reported-by: Andrej Picej <andrej.picej@norik.com> Tested-by: Andrej Picej <andrej.picej@norik.com>

Usually, removing barebox_set_hostname() would let barebox generate it automatically. But in this case, the name would look less informative. For example "2-model-b". So, make board code generate something usable, for example "rpi-2-model-b" Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Link: https://lore.barebox.org/20220203104552.3158202-6-o.rempel@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
