Vamshi Gajjela	ffdbeee9f6	sdmmc: Add erase command-38. Support erase/trim/discard/sanitize ... options. Erase command (38) for SD cards allows option for erase/dicard/fule operation at block level and for MMC cards supports option for discard/trim at block level. When Sanitize is executed only the portion of data that was unmapped by a Discard command shall be removed by the Sanitize command. Unit test cases added to verify ERASE feature in SD/SDSPI mode. TRIM/DISCARD/SANITIZE tests for eMMC devices. Closes https://github.com/espressif/esp-idf/pull/7635 Closes https://github.com/espressif/esp-idf/issues/7623	2022-03-05 16:02:01 +05:30
