sandbox: remap memory load addresses 2025-03-08T14:27:22+00:00 Svyatoslav Ryhel clamor95@gmail.com 2025-03-07T08:59:57+00:00 e6883b6b30784a529fbccd74f3226ad493d15116 The existing memory layout places the bloblist at 0xb000 and the fdt at 0x100, resulting in a 0xaf00 size constraint for the fdt. This constraint has been reached. Lets modify the layout by moving the bloblist to 0x100, device tree to 0x1000 and placing early memory allocation after pre-console buffer at 0xf4000. This should guarantee sufficient memory allocation for future expansion. Signed-off-by: Svyatoslav Ryhel <clamor95@gmail.com>

Merge patch series "Fix various bugs" 2024-09-18T19:07:19+00:00 Tom Rini trini@konsulko.com 2024-09-18T19:07:19+00:00 c17805e19b9335e1fb5295c81b59eddf88d1b9ec Simon Glass <sjg@chromium.org> says: This series includes the patches needed to make make the EFI 'boot' test work.

sandbox: Change the range used for memory-mapping tags 2024-09-18T19:01:00+00:00 Simon Glass sjg@chromium.org 2024-09-01T22:26:23+00:00 df2c5941a68031b0c0faeecab4132140dcc6b771 Sandbox keeps a table of addresses which map to pointers which are outside its emulated DRAM. The current range from 10000000 conflicts with the PCI range, meaning that if PCI mapping is on, that particular address can be decoded by PCI instead of the table. Fix this by moving the range up to the top of memory. Update the docs while we are here. Signed-off-by: Simon Glass <sjg@chromium.org>

sandbox: move the TCG event log to the start of ram memory 2024-09-03T20:08:50+00:00 Sughosh Ganu sughosh.ganu@linaro.org 2024-08-26T11:59:32+00:00 9b19e207a9768acdaac5a496fecf317e48a54c7a The TCG event log buffer is being set at the end of ram memory. This region of memory is to be reserved as LMB_NOMAP memory in the LMB memory map. The current location of this buffer overlaps with the memory region reserved for the U-Boot image, which is at the top of the usable memory. This worked earlier as the LMB memory map was not global but caller specific, but fails now because of the overlap. Move the TCG event log buffer to the start of the ram memory region instead. Move the location of the early trace buffer and the load buffer for U-Boot(spl boot) accordingly. Signed-off-by: Sughosh Ganu <sughosh.ganu@linaro.org> Reviewed-by: Simon Glass <sjg@chromium.org>
