Pali Rohár d17ab6e128 nvme: Do not allocate 8kB buffer on stack ... Calling 'nvme scan' followed by 'nvme detail' crashes U-Boot on Turris Omnia with the following error: undefined instruction pc : [<0a000000>] lr : [<7ff80bfc>] reloc pc : [<8a8c0000>] lr : [<00840bfc>] sp : 7fb2b908 ip : 0000002a fp : 02000000 r10: 04000000 r9 : 7fb2fed0 r8 : e1000000 r7 : 0c000000 r6 : 03000000 r5 : 06000000 r4 : 01000000 r3 : 7fb30928 r2 : 7fb30928 r1 : 00000000 r0 : 00000000 Flags: nZCv IRQs off FIQs off Mode SVC_32 Code: 0f0fb4f0 0f0fb4f0 0f0fb4f0 0f0fb4f0 (f0f04b0f) Resetting CPU ... This happens when nvme_print_info() tries to return to the caller. It looks like this error is caused by trying to allocate 8 KiB of memory on the stack by the two uses of ALLOC_CACHE_ALIGN_BUFFER(). Use malloc_cache_aligned() to allocate this memory dynamically instead. This fixes 'nvme detail' on Turris Omnia. Note that similar change was applied to file drivers/nvme/nvme.c in past by commit 2f83481dff ("nvme: use page-aligned buffer for identify command").
