Analysis was based on value of EXT_CSD_BOOT_INFO, not CARD_TYPE. CARD_TYPE should be handled using bitmask, not values. Signed-off-by: Oleg Matcovschi <olegm@lab126.com> Signed-off-by: Chris Ball <cjb@laptop.org>

Improve "extcsd read" output of the registers. Right-shift by 3 of EXT_CSD_BOOT_CFG_EN bits. Expand the EXT_CSD_BOOT_CFG_ACC bit mask to 0x7. Add case 3 RPMB partition. Signed-off-by: Mario Schuknecht <mario.schuknecht@dresearch-fe.de> Signed-off-by: Chris Ball <cjb@laptop.org>

This patch adds a method to trigger Sanitize command to MMC. The Sanitize command is used for deleting the unmapped memory region of the MMC device. Signed-off-by: Yaniv Gardi <ygardi@codeaurora.org> Acked-by: Subhash Jadavani <subhashj@codeaurora.org> Signed-off-by: Chris Ball <cjb@laptop.org>

This patch added the method to enable the bkops. In ext_csd register, BKOPS_EN bit is one-time programable. So if you want to use the bkops, use the this command. $ mmc bkops enable /dev/mmcblk0 Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Reviewd-by: Venkatraman S <svenkatr@ti.com> Signed-off-by: Chris Ball <cjb@laptop.org>

In this patch, we add a utility to disable emulation mode in eMMC-4.5. This is done to increase the data sector size to 4KB.

This adds a new option to enable the boot from eMMC by writing to the 179 ext_csd register. The example below shows as to enable the mmcblk0boot0 partition and also set/reset the ACK bit). $ ./mmc bootpart enable 1 1 /dev/mmcblk0boot0 $ ./mmc extcsd read /dev/mmcblk0boot0 | grep PARTITION_CON Boot configuration bytes [PARTITION_CONFIG: 0x49] Reported-by: Youssef TRIKI <youssef.triki@st.com> Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: Chris Ball <cjb@laptop.org>

This leaves "extcsd read" pointing to Giuseppe's code. Also, abstract out the writeprotect code so that there's only one shared implementation in print_writeprotect_status(), used by both "extcsd read" and "writeprotect get". Signed-off-by: Chris Ball <cjb@laptop.org>

This patch enhances the debug information reported for the mmc card by parsing the extended CSD registers obviously according to all the current specifications. I have no HW to test eMMC 4.5 at this moment. In any case, the patch supports JEDEC Standard No. 84-B45. No issues on JESD84-A441 and older specs raised on my side. This patch indeed want to start providing a full parsing of the all EXT_CSD registers in the following layout: Name [FIELD: <value>] Voluntarily, I added the FIELD because it can actually help on searching though the SPEC in case of doubts. In fact, in this stage, not all the register bits are yet parsed. Currently this has been done for a small subset of registers (e.g. 173, 160 ...) where IMO it's quite useful for an end-user to get some details. I do hope this will be improved in the near feature (also for write operations). P.S. The original patch posted time ago for the Kernel has been reviewed-by Sebastian Rasmussen, acked-by: Linus Walleij and reported by Youssef Tiki.
