Mahavir Jain	deab1da6f2	fix(esp_mm): for existing mmap region, consider new offset for virtual addr ... While returning virtual address for existing memory mapped region, newly supplied offset from the physical address was not getting considered. This was a regression present from ESP-IDF 5.1 release. Added test case in spi_flash component that fails without this fix. Closes https://github.com/espressif/esp-idf/issues/13929	2024-07-15 12:42:45 +08:00

Armando	98892a3288	esp_mm: correct mmap reserved irom and drom size ... Prior to this commit, we don't consider the offset of the irom vaddr start. If the offset + size is bigger than the MMU page size, for example: MMU page size: 0x10000 irom vaddr: 0x4200_0800, so offset = 0x800 irom size: 0xF900 offset + size = 0x10100 Under this condition, the 0x4200_0000 ~ 0x4202_0000, two MMU pages are used. With this commit, when reserving the irom and drom, we take the offset into consideration as well.	2023-02-07 20:23:53 +08:00
