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.

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.

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.

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.

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

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.

29c6eab6dc components/spi_flash: call SPIUnlock only once
This fixes the performance impact for spi_flash_write and spi_flash_erase.
With this change, NVS init in single core mode takes about 50ms (compared to >2seconds before that).

NVS and WiFi stack can also run in dual core mode now.

3b1c3dab4b Name component makefiles component.mk instead of Makefile
Fixes problems with Eclipse trying to build in directories it shouldn't.

This is a breaking change for existing repositories, they need to rename
any component Makefiles to component.mk and rename their references to
$(IDF_PATH)/make/component.mk to $(IDF_PATH)/make/component_common.mk

f853f94335 Use IDF_PATH instead of SDK_PATH for the environment variable pointing to esp-idf
This will require a matching change in all projects using ESP-IDF.
