d77c74770a bugfix(flash): add flash config in app startup
We fixed some flash bugs in bootloader, but for the users used the old
vrsion bootloader, they can not fix these bugs via OTA, the solution is
add these updates in app startup.

These updates include:
1. SPI flash gpio matrix and drive strength configuration
2. SPI flash clock configuration
3. SPI flash read dummy configuration
4. SPI flash cs timing configuration
5. Update flash id of g_rom_flashchip

399d2d2605 all: Using xxx_periph.h
Using xxx_periph.h in whole IDF instead of xxx_reg.h, xxx_struct.h, xxx_channel.h ... .

Cleaned up header files from unnecessary headers (releated to soc/... headers).

d68f1907ef bugfix(flash): improve flash dio read timing
When flash work in DIO Mode, in order to ensure the fast read mode of flash
is a fixed value, we merged the mode bits into address part, and the fast
read mode value is 0 (the default value).

448d32bc53 bugfix(psram): improve spi cs timing settings for psram
1. remove redundant SPI clock settings, use rom functions to set clock.
2. remove redundant SPI cs setup and hold settings.
3. for old 32Mbit psram, cs hold time must only be 0.5T due to the special driving mode.(cs_setup = 0; cs_hold = 0)
4. for new 64Mbit psram, cs hold time is recommended to be 2.5T. (cs_setup = 1, cs_setup_time = 0;cs_hold = 1, cs_hold_time = 1)

bd8733f74f feature(psram): add psram support for esp32-pico chip
1. esp32-pico use standard spi driver to access psram
2. for esp32-pico, flash and psram share the clock
3. for esp32-pico, psram cs io can be overwrite via menuconfig

a0beff99d2 bugfix(psram): fix psram size acquisition method
1. Use BIT[7:5] of EID to determine psram size
2. Add ID support for 16Mbit psram
3. Remove module reset on SPI1
4. Confirmed with the vendor that only the old 32Mbit psram need special clock timing. For other psram chips, we should use standard QPI mode.

a10b7e892c bugfix(psram): fix psram driver
1. remove use EID to distinguish psram voltage
2. 1V8 64Mbit psram and 3V3 64Mbit psram use the same psram driver(standard spi interface)
3. set cs hold time register as 1

6e9c59bfc3 feature(psram): add support for 64MBit psram of 1.8v and 3.3v.
1. Add reading psram EID.
2. Configure different clock mode for different EID.
3. add API to get psram size and voltage.
4. Remove unnecessary VSPI claim.

For 32MBit@1.8V and 64MBit@3.3V psram, there should be 2 extra clock cycles after CS get high level.
For 64MBit@1.8 psram, we can just use standard SPI protocol to drive the psram. We also need to increase the HOLD time for CS in this case.

EID for psram:
32MBit 1.8v: 0x20
64MBit 1.8v: 0x26
64MBit 3.3v: 0x46

d775cc4c4c soc: Fix description of rtc_config_t.tieh, add macros
Usage of TIEH was correct but description had 1.8V & 3.3V backwards.

Add macro definitions for TIEH values to improve readability.

b1dcb52fec feature(psram): configure flash and psram speed during runtime
1. Bootloader reads SPI configuration from bin header, so that the burning configuration can be different with compiling configuration.
2. Psram mode init will overwrite original flash speed mode, so that users can change psram and flash speed after OTA.
3. Flash read mode(QIO/DIO…) will not be changed in app bin. It is decided by bootloader, OTA can not change this mode.
4. Add read flash ID function, and save flash ID in g_rom_flashchip
5. Set drive ability for all related GPIOs
6. Check raise VDDSDIO voltage in 80Mhz mode
7. Add check flash ID and update settings in bootloader
8. Read flash ID once and keep in global variable
9. Read flash image header once and reuse the result

Tested cases:
1. Test new and old version of bootloader
boot Flash 20M —> app Flash 80M + Psram 80M
boot Flash 40M —> app Flash 80M + Psram 80M
boot Flash 80M —> app Flash 80M + Psram 80M
boot Flash 20M —> app Flash 80M + Psram 40M
boot Flash 40M —> app Flash 80M + Psram 40M
boot Flash 80M —> app Flash 80M + Psram 40M
boot Flash 20M —> app Flash 40M + Psram 40M
boot Flash 40M —> app Flash 40M + Psram 40M
boot Flash 80M —> app Flash 40M + Psram 40M
2. Working after esp_restart reboot.

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
