to sector (4k) erase.

f7ac41c2da spi_flash: Add option to log warnings if (spuriously) writing zero bits to ones
Won't work for SPIFFS, maybe some other implementations?

7a924bd85a spi_flash: Expose an accessor the current SPI flash guard functions
Change places which uses g_flash_guard_default_ops to use this. Probably exact same data, but a bit
cleaner.

11d2db40f4 spi_flash: Fix SPI flash write alignment/size bugs
* Writing >4 bytes to unaligned offsets would fail
* Writiing data from flash would fail (wrong buffer was used)
* Writing >8192 bytes from RAM would over-write data multiple times

Adds test cases for the above.

d8fda48551 spi_flash: Split large SPI flash operations into parts, allowing preemption
* Erase range operations allow preemption after each block or sector.
* Write operations allow preemption every 8KB of data.
* Reado operations allow preemption every 16KB of data.

cbb71baca9 spi_flash: protect spi_flash_unlock
spi_flash_unlock was missing spi_flash_guard_start, which caused cache
to be enabled during unlock operation, causing hard-to-trace crashes
and cache data corruption.

adc590ff69 spi_flash_write_encrypted: Allow 16-byte aligned block writes
As each 32 byte write has two identical 16 byte AES blocks, it's
possible to write them separately.

36ccdee6ec spi_flash: Flush flash cache if flash_mmap()ing a written-to page
Without this, it's possible for stale information to be read from
cache via mmap, even if the MMU table entry had been invalidated
prior to writing flash (if  the same MMU table entry was re-used after
writing flash.)

075446318d spi_flash: define spi_flash_guard_{start,stop} with IRAM_ATTR
These functions are marked as inline and are called from functions which are in IRAM.
In release (-Os) builds, the compiler may decide not to inline these functions.
Placing these functions into IRAM explicitly works around this.

bab1d49f1f Merge branch 'feature/esptool_flash_encryption' into 'master'
Flash encryption support

Flash encryption support in build system, tooling

To come in future MR:
* On-device key generation on first boot (for production devices), need to finalise testing of bootloader entropy seeding.
* spi_flash_encrypted_write to support non-32-byte block writes (at least optionally.)
* I think a lot of the bootloader_support component can possibly be rolled into "spiflash" and other components, to use a common API.

be53a6950c spi_flash_erase_range: Allow for 32KB blocks not 64KB blocks
SPI flash hardware sends 52h command, which is a 32KB erase.

There is a matching bug in the ROM SPIEraseArea code, unless
flashchip->block_size is modified first.

2119b98469 spi_flash: remove unnecessary src pointer alignment check in spi_flash_write
ROM SPIWrite routine can work with unaligned sources, so this check is unnecessary.
Furthermore, it breaks nvs_set_str and nvs_get_blob when data pointer is unaligned.
Also fix stray backslash in COUNTER_STOP macro

2c5340d47e spi_flash: change argument types
spi_flash_read and spi_flash_write currently have a limitation that source and destination must be word-aligned.
This can be fixed by adding code paths for various unaligned scenarios, but function signatures also need to be adjusted.
As a first step (since we are pre-1.0 and can still change function signatures) alignment checks are added, and pointer types are relaxed to uint8_t.
Later we will add handling of unaligned operations.
This change also introduces spi_flash_erase_range and spi_flash_get_chip_size functions.

We probably need something like spi_flash_chip_size_detect which will detect actual chip size.
This is to allow single application binary to be used on a variety of boards and modules.
