Table 41 of the JEDEC standard for eMMC says that bit 31 of the command argument is obsolete when issuing the ERASE command (CMD38) on page 115 of this document: http://www.jedec.org/sites/default/files/docs/jesd84-B45.pdf
The SD Card Association Physical Layer Simplified Specification also makes no mention of the use of bit 31. https://www.sdcard.org/downloads/pls/part1_410.pdf
The Linux kernel distinguishes between secure (bit 31 set) and non-secure erase, and this patch copies the macro names from include/linux/mmc/core.h.
