5361c08989 heap: Support adding new heap regions at runtime
To facilitate this, the list of registered heap regions is now a linked list
(allowing entries to be appended at runtime.)

34372a091c Add initial SPI RAM support. This adds support for an ESP-PSRAM32 chip connected to the default flash pins and GPIO 16 and 17. The RAM is mapped to address 0x3F800000, but otherwise ignored by esp-idf as of yet. 2017-09-04 12:05:49 +08:00

4776f73ca4 Disable some peripheral clocks when cpu starts
All peripheral clocks are default enabled after chip is powered on.
    When CPU starts, if reset reason is CPU reset, disable those clocks
    that are not enabled before reset. Otherwise, disable all those
    useless clocks.
    These peripheral clocks must be enabled when the peripherals are
    initialized and disabled when they are deinitialized.

99fe61716c startup: Add assertion checks around various initialisation sequences

2b0f623259 bootloader/early boot: Error out if >192KB of static DRAM is allocated (temporary fix)
Currently the last 128KB of DRAM is reserved for the bootloader & early boot stacks. This means if >192KB of static DRAM
is allocated, the only available heap is this region - which is disabled until the scheduler starts. As a result, you
get either heap corruption on early boot if the static data overlaps startup heap (leading to very weird errors), or
FreeRTOS will fail to start when it can't malloc() anything.

Long term fix is to move the stacks & bootloader data to the very end of RAM, and only reserve that part for early
boot. This is a little fiddly because of also wanting to make sure this memory is not preemptively fragmented when it
gets reintroduced to the heap. This will become more important if/when we have more static allocation options in the
future.

For now, these errors make it clear why the boot has failed.

f698a1b2d3 Add missing support for C++ exceptions
Specifying -fexceptions for the compiler is not enough.

- add necessary zero padding after .eh_frame section
- link .gcc_except_table_table in a way flash script does not complain
- call __registrer_frame_info before global constructors

Kudos jcmvbkbc for the necessary help.

8d43859b6a esp32: SEGGER SystemView Tracing Support
Implements support for system level traces compatible with SEGGER
SystemView tool on top of ESP32 application tracing module.
That kind of traces can help to analyse program's behaviour.
SystemView can show timeline of tasks/ISRs execution, context switches,
statistics related to the CPUs' load distribution etc.

Also this commit adds useful feature to ESP32 application tracing module:
 - Trace data buffering is implemented to handle temporary peaks of events load

f327a9b1cf esp32: don’t reset APP CPU if it was already reset by OpenOCD
When ‘reset halt’ command is executed, OpenOCD will take the APP CPU
out of reset and enable the clock. At this point, user can set a
breakpoint on code which will run on APP CPU. Previously, app startup
code would do another reset of APP CPU, thereby removing any breakpoints
which may have been set. This change makes APP CPU reset conditional on
DPORT_APPCPU_CLKGATE_EN bit, which is 0 by default but is set to 1 by
OpenOCD after reset.

6353bc40d7 Add support for 32k XTAL as RTC_SLOW_CLK source
- RTC_CNTL_SLOWCLK_FREQ define is removed; rtc_clk_slow_freq_get_hz
  function can be used instead to get an approximate RTC_SLOW_CLK
  frequency

- Clock calibration is performed at startup. The value is saved and used
  for timekeeping and when entering deep sleep.

- When using the 32k XTAL, startup code will wait for the oscillator to
  start up. This can be possibly optimized by starting a separate task
  to wait for oscillator startup, and performing clock switch in that
  task.

- Fix a bug that 32k XTAL would be disabled in rtc_clk_init.

- Fix a rounding error in rtc_clk_cal, which caused systematic frequency
  error.

- Fix an overflow bug which caused rtc_clk_cal to timeout early if the
  slow_clk_cycles argument would exceed certain value

- Improve 32k XTAL oscillator startup time by introducing bootstrapping
  code, which uses internal pullup/pulldown resistors on 32K_N/32K_P
  pins to set better initial conditions for the oscillator.

f73c6f875c Merge branch 'bugfix/dont_log_before_bss_inited' into 'master'
Remove ESP_EARLY_LOGI before bss is initialized; it crashes the CPU

There's an ESP_EARLY_LOGI line that can get called before the BSS is initialized; the early logging code doesn't cope well with that: it checks if FreeRTOS is up, but the variables it uses for that contains garbage because it isn't cleared yet, giving the wrong result. The logging code then tries to set a mux, crashing the entire system. This patch removes the log line and adds a warning at the BSS initialization line not to do anything complex before that point.

Fixes https://github.com/espressif/esp-idf/issues/523

55f1a63faf esp32: Adds functionality for application tracing over JTAG
- Implements application tracing module which allows to send arbitrary
   data to host over JTAG. This feature is useful for analyzing
   program modules behavior, dumping run-time application data etc.
 - Implements printf-like logging functions on top of apptrace module.
   This feature is a kind of semihosted printf functionality with lower
   overhead and impact on system behaviour as compared to standard printf.

1. Add disable PHY and RF when WiFi and BT are both disabled(including call sniffer disable API).

2. Do not init PHY and RF when cpu start. Init PHY and RF when call Wifi or BT start APIs(including sniffer enable API).

3. Add a temporary lib: librtc_clk.a and will delete it when CPU frequency switching function is done.

4. Add an function to get OS tick rate.

5. Do not put the whole pp.a in iram0, only put lmac.o, ieee80211_misc.o, ets_time.o and wdev.o in iram0.

777816cb99 phy_init: don’t rewrite valid calibration data
In the default PHY init routine, calibration data is loaded from NVS.
Most of the time the incremental changes to calibration will be fairly
small, so we don’t need to rewrite the existing calibration data stored
in the NVS.

Possible enhancement to be done in the future: expose a function in PHY
library to tell how big was the change in calibration data. If the
change was significant, then calibration data stored in NVS should be
updated.

13d802262a cpu_start: disable boot watchdog only after starting the main task
Boot watchdogs were disabled very early in startup code. It was possible to introduce an infinite loop anywhere in the many functions called from startup code, and this would not be detected by interrupt watchdog and task watchdog. This change postpones disabling of boot watchdogs to the point when the scheduler is running. Also replaces register expressed using integer address with a name.
