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

Ivan Grokhotkov	ab68b9d90d	soc,sdmmc: fix build failures when NDEBUG is used ... Use explicit error checking instead of asserts, use SOC_LOG to print error/warning messages where needed.	2018-10-15 14:57:12 +08:00
Ivan Grokhotkov	78fab8a0f9	sdmmc: implement partial DDR support ... Works for 3.3V eMMC in 4 line mode. Not implemented: - DDR mode for SD cards (UHS-I) also need voltage to be switched to 1.8V. - 8-line DDR mode for eMMC to be implemented later.	2018-08-30 13:11:54 +08:00
