* [PUYA] Applied ESPeasy puya_v3.patch Applied the patch to get the starting point as described in https://github.com/esp8266/Arduino/issues/5493 * [PUYA] Only allocate memory when PUYA detected core 2.5.0 PUYA patch, no puya: Description Function #calls call/sec min (ms) Avg (ms) max (ms) Save File 4 0.25 34.755 45.264 67.620 Free Mem: 16168 core 2.5.0 PUYA patch, Faked Puya detect: Description Function #calls call/sec min (ms) Avg (ms) max (ms) Save File 2 0.04 41.332 57.544 73.756 Free Mem: 11560 * [PUYA] Check for PUYA chip as soon as possible at boot Check for PUYA chip in call for `getFlashChipId()` This will only be done once and the result of the get function is also cached. * [PUYA] Use limited buffer (512 byte) allocated at first write No need to allocate a buffer when not writing to flash. The default buffer size is 512 bytes, which is 2 pages in the flash chip. * [PUYA] Lower PUYA flash buffer to 1 page (256 B) As discussed here: https://github.com/esp8266/Arduino/issues/5493#issuecomment-447543279 * [PUYA] Fix indents naming and return conditions * [PUYA] Move Puya write code to spi_flash_write_puya * [PUYA] Make spi_flash_write_puya static and define PUYA_SUPPORT * [PUYA] Add some SPI flash vendor IDs As requested by @igrr https://github.com/esp8266/Arduino/pull/5504#discussion_r242016184 * [PUYA] All suggested changes.
