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.

f7e8856520 component/esp32 : fix dualcore bug
1. When dual core cpu run access DPORT register, must do protection.
2. If access DPORT register, must use DPORT_REG_READ/DPORT_REG_WRITE and DPORT_XXX register operation macro.

85e76a7cfc spiflash ROM functions: Remove Quad I/O mode enable/disable code from flash ROM functions
Confusion here is that original ROM has two functions:

* SPIReadModeCnfig() - sets mode, calls enable_qio_mode/disable_qio_mode
* SPIMasterReadModeCnfig() - As above, but doesn't set QIO mode in status register

However we never want to use the ROM method to set/clear QIO mode flag, as not all flash chips work this way. Instead we
do it in flash_qio_mode.c in bootloader.

So in both cases (ROM or "patched ROM") we now call SPIMasterReadModeCnfig(), which is now named
esp_rom_spiflash_config_readmode().

92436021ab spi_flash: fix race condition in s_flash_op_complete access
Flash operation complete flag was cleared by the core initiating flash
operation. If the other core was running an ISR, then IPC task could
be late to enter the loop to check s_flash_op_complete by the time next
flash operation started. If the flag is cleared on the CPU waiting on
this flag, then the race condition can not happen.

d790300215 spi_flash: fix stale data being read from mmaped region
The issue that cache entries are not invalidated correctly sometimes
can also be reproduced for non-encrypted flash as well.
This change updates the workaround to do Cache_Flush, enabling it for
non-encrypted flash, and adds a unit test.

e76c187efb spi_flash: protect esp_intr_noniram_{disable,enable} in 1-core config
MR !441 (7c155ab) has fixed issue with esp_intr_noniram_{disable,enable}
calls not being properly protected by spi_flash_op_{lock,unlock}.
Unit test was added, but the unit test environment tests only dual-core
config. Similar issue was present in the code path for the single-core
config, where esp_intr_noniram_{disable,enable} calls were unprotected.

This change fixes the protection issue and updates the unit test to
run properly in single core config as well.

The issue with running unit tests for single core config will be
addressed in a separate MR.

d8aae55eeb Flash encryption: Temporary fix for issue with stale cache reads
Seems doing certain kinds of short reads while flash encryption is

7c155ab647 Merge branch 'bugfix/flash_op_unpinned_task' into 'master'
fixes for issues observed when using spi_flash

This MR fixes three unrelated issues:

- Race condition in spi_flash_enable_interrupts_caches_and_other_cpu
  when operations on unpinned tasks are performed.
  The issue is reported in https://github.com/espressif/esp-idf/pull/258

- esp_intr_noniram_disable doesn’t disable interrupts when compiled in
  release mode. This issue manifested itself with an illegal instruction
  exception when task WDT ISR was called at the time when flash was
  disabled.
  Fixes https://github.com/espressif/esp-idf/issues/263.

- Tick hooks on CPU1 were not called if CPU0 scheduler was disabled for
  significant amount of time (which could happen when doing flash erase).
  The issue manifested itself as “INT WDT timeout on core 1” error.
  Fixes https://github.com/espressif/esp-idf/issues/219.

4676d159ad spi_flash: fix race condition when doing operations in unpinned tasks
spi_flash_enable_interrupts_caches_and_other_cpu function used to enable
non-IRAM interrupts after giving up flash operation lock, which would
cause problems if another task was waiting on the lock to start a flash
operation. In fact, non-IRAM interrupts should be re-enabled before the
task scheduler is resumed. Otherwise non-pinned task can be moved to the
other CPU due to preemption, causing esp_intr_noniram_enable to be
called on the other CPU, causing an abort to be triggered.

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.

bf57594ebe Merge branch 'feature/intr_alloc' into 'master'
Add dynamic interrupt allocation mechanism

This adds:
- Dynamic allocation of interrupts. Pass it the features of the interrupt you want, it'll set you up with an int.
- Shared interrupts. Enables multiple peripheral drivers to use the same interrupt. 
- Marking what interrupts are fully executable from IRAM; if an int isn't marked like that it will get disabled once flash cache gets disabled.

Also:
- Modifies driver to be in line with these changes
