037c079e9a esp32: Refactor backtrace and add esp_backtrace_print()
This commit refactors backtracing within the panic handler so that a common
function esp_backtrace_get_next_frame() is used iteratively to traverse a
callstack.

A esp_backtrace_print() function has also be added that allows the printing
of a backtrace at runtime. The esp_backtrace_print() function allows unity to
print the backtrace of failed test cases and jump back to the main test menu
without the need reset the chip. esp_backtrace_print() can also be used as a
debugging function by users.

- esp_stack_ptr_is_sane() moved to soc_memory_layout.h
- removed uncessary includes of "esp_debug_helpers.h"

562af8f65e global: move the soc component out of the common list
This MR removes the common dependency from every IDF components to the SOC component.

Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components.
But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components.

In CMAKE, we have two kinds of header visibilities (set by include path visibility):

(Assume component A --(depends on)--> B, B is the current component)

1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B)
2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only)

and we have two kinds of depending ways:

(Assume component A --(depends on)--> B --(depends on)--> C, B is the current component)

1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B)
2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B)

1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default.
2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it.
3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers
4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link)

This is a breaking change. Previous code may depends on the long include chain.
You may need to include the following headers for some files after this commit:

- soc/soc.h
- soc/soc_memory_layout.h
- driver/gpio.h
- esp_sleep.h

The major broken include chain includes:

1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h.
2. ets_sys.h no longer includes soc/soc.h
3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h

some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h

8bba348528 aes/sha/mpi: Bugfix a use of shared registers.
This commit resolves a blocking in esp_aes_block function.

Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.

Fix some related issue with shared using of AES SHA RSA accelerators.

4132834faa test: fix the unit test fail issue under single_core config
Introduced in 97e3542947.

The previous commit frees the IRAM part when single core, but doesn't
change the memory layout functions. The unit test mallocs IRAM memory
from the heap, accidently into the new-released region, which doesn't
match the memory layout function.

This commit update the memory layout function to fix this.

22b840f3df bootloader: don’t reload RTC_FAST DRAM after deep sleep
When CONFIG_ESP32_RTCDATA_IN_FAST_MEM is enabled, RTC data is placed
into RTC_FAST memory region, viewed from the data bus. However the
bootloader was missing a check that this region should not be
overwritten after deep sleep, which caused .rtc.bss segment to loose
its contents after wakeup.

2e31cce390 soc/rtc: CPU frequency settings refactoring
Previous APIs used to set CPU frequency used CPU frequencies listed in
rtc_cpu_freq_t enumeration. This was problematic for two reasons.
First, supporting many possible frequency values obtained by dividing
XTAL frequency was hard, as every value would have to be listed in
the enumeration. Since different base XTAL frequencies are supported,
this further complicated things, since not all of these divided
frequencies would be valid for any given XTAL frequency. Second,
having to deal with enumeration values often involved switch
statements to convert between enumeration and MHz values, handle
PLL/XTAL frequencies separately, etc.

This change introduces rtc_cpu_freq_config_t structure, which contains
CPU frequency (in MHz) and information on how this frequency has to
be generated: clock source (XTAL/PLL), source frequency, clock
divider value. More fields can be added to this structure in the
future. This structure simplifies many parts of the code, since both
frequency value and frequency generation settings can be accessed in
any place in code without the need for conversions.

Additionally, this change adds setting of REF_TICK dividers to support
frequencies lower then XTAL with DFS.

f7749e18a8 gpio: Bitmask overflow fix in gpio_reset_pin
For pins 32 and up the BIT(nr) macro used here overflowed,
causing undetermined GPIO pins to be reset.
Example: freeing SPI device/bus where CS is on pin 33
caused debug UART to cease communication, TXD0 was
disabled.

Fixed as BIT64(nr) macro, to be used elsewhere as needed.
For example in definitions like GPIO_SEL_32..GPIO_SEL_39.

f7df532ec0 bugfix/rtc_clk_32k_bootstrap: Fix starting 32k RTC
1. External 32kHz crystal is started for too long or it may not start at all. It is often observed at the first start.
2. At the first start, it is possible that the crystal did not start. And the recorded period was recorded as 0. Which led to a division error by zero during the transition to the deep sleep mode (Maybe somewhere else).
3. Added a unit test to test a new method of oscillation an external crystal.
4. Added a new method of oscillating of an external crystal. The legs of the crystal are fed with a 32 kHz frequency.

The new method eliminates these errors.

Added unit test: `\esp-idf\components\soc\esp32\test\test_rtc_clk.c`: `make TEST_COMPONENTS=soc`
- 8 Test starting external RTC crystal. Will pass.

`Bootstrap cycles for external 32kHz crystal` - is specified in the file Kconfig by default 100.

QA tested a new method of oscillation the crystal on 25 boards. The supply of square waves on the crystal showed a 100% result in contrast to the previous method of launching the crystal. After the tests, the old method was deleted.

8b1277c55f efuse/add cpu freq rating
This commit adds support for CPU max freqeuency rating
bits in CPU. Bootloader will now print an error if attempting
to 160MHz rated ESP32 at 240MHz.

EFUSE_CHIP_VER_RESERVE has been replaced by the
frequency rating bits. Dependancies on EFUSE_CHIP_VER_RESERVE
have been changed to use EFUSE_CHIP_VER_PKG

0c9e2c0fba esp_adc_cal/Remove lookup table
This commit removes the lookup table mode due to inferior performance when compared
to linear mode under attenuation 0, 1 and 2. However small portions of the lookup table
are kept for the higher voltages of atten 3 (above ADC reading 2880). That voltage range
in atten 3 has non linear characteristics making the LUT performan better than linear mode.

70ab924dbb Especially when internal memory fills up, some FreeRTOS structures (queues etc) get allocated in psram. These structures also contain a spinlock, which needs an atomic-compare-swap operation to work. The psram hardware, however, does not support this operation. As a workaround, this patch detects these spinlocks and will, instead of S32C1I, use equivalent C-code to simulate the behaviour, with an (internal) mux for atomicity. 2018-02-02 17:11:06 +08:00

4297c337f9 esp32: Add IO_MUX_GPIOxx register names to match iomux names used in TRM
The TRM describes IOMUX registers are IO_MUX_x_REG for x in GPIO0-39.

Until now ESP-IDF describes them as PERIPHS_IO_MUX_(pinname)_U

This commit adds additional IOMUX register names which match the ones used in the TRM.
