While the bootrom erases or programs the flash, the QMI is in direct mode, and an access to the XIP space (flash or PSRAM) gives a bus fault. The flash MTD driver accessed it in two cases: - The data to program was in flash or PSRAM. flash_range_program() read it during the operation. Now the driver copies each such page to an SRAM buffer first. - The caller's stack was in PSRAM. This is the normal case with RP23XX_PSRAM_HEAP_USER, and possible with RP23XX_PSRAM_HEAP_SINGLE. The operation pushed to that stack. Now the driver switches to a small SRAM stack for the operation if the stack is in the XIP space. The operation data is static (SRAM) since the previous commit.
