This change reduces chances that a large .bss segment will push .data all the way into
0x3ffe1320 — 0x3ffe5320 range where the bootloader stack is, creating a problem when
bootloader will be loading application into memory.
With this change, .data would need to be at least 200k big to cause problems.
Modify bootloader dram_seg from address 0x3ffc0000 to 0x3fff0000, len from
0x20000 to 0x10000. Please be notified that this is just a workaround for
fixing app data overwrite bootloader data issue!

bugfix: uart event mismatch
Fix bug of uart frame error and parity error interrupt mismatch in driver code, which will cause the corresponding interrupt can not be cleared correctly, and will finally cause a interrupt watch dog.

GPIO driver: add per-pin interrupt handlers
1. add ISR handler apis so that users of different layers can hook their own isr handler on different GPIO.
Audio project has different software layers, they need different gpio isr handler for layer instead of processing all GPIO interrupts in one handler.
If this kind of calling a handler from isr is not proper, please kindly point out.
2. add gpio example code.
3. update gpio doc.

freertos: fix dual core issue
This commit try to fix dual issue tw9313 raised by QA
1. Put per-core data into critical session or interrupt disabled/enabled session
2. Idle task may have problem when it terminate the task in both core
See merge request !333
1. The transmitting mode of the packets from LWIP to MAC is changed from synchronous to asynchronous.
2. The receive buf mode : support pointer mode and copy mode.
3. Add get phy status func used to config mac register.
1. Fix bug of uart frame error and parity error interrupt mismatch in driver code, which will cause the corresponding interrupt can not be cleared correctly, and will finally cause a interrupt watch dog.
2. Add gpio pull-up for rx pin and cts pin.
This commit fixes:
1. xTaskGetCurrentTaskHandle may return wrong TCB when current task switch to a different core
2. Idle task may have problem when it terminate the task in both core
Minor fixes from various sources
- Fix memory debugging code. Noticed by Tuan.
- intr_enable/disable should be in IRAM. Noticed by rojer
- Still old timer code in examples in doxygen comments. Noticed on the forum by jumjum123
- Timer example was broken. Noticed on the forum by jumjum123

ULP: add new instructions, fix bugs, add tests
This adds peripheral register read and write instructions, an instruction to wake the SoC from deep sleep, and some tests.
Also fixes two bugs: ANDI instruction definition, and running the ULP when in deep sleep mode.
See merge request !317
Fix exception handler to jump to correct vector instead of crashing to the double exception vector.
One-character fix... basically, this caused the exception handler to crash into the double-exception handler instead of nicy panic'ing.

Secure boot: Option for app & partition table signing to happen outside build system
Allows for a remote signing server, private signing key does not need to be on the build system.

local-only communication.
In case of the AP interface, if gw is not set, do not offer it.

Starting the ULP using SENS_SAR_START_FORCE_REG doesn’t disable clock gating of RTC fast clock.
When SoC goes into deep sleep mode, RTC fast clock gets gated, so ULP can no longer run.
Instead, it has to be started using the timer (RTC_CNTL_ULP_CP_SLP_TIMER_EN bit).
When ULP is enabled by the timer, clock also gets enabled.
