[U-Boot] [PATCH 1/2] eMMC: add support for operations in RPMB partition

Hello, Pierre.

Could you please help me to understand why you used R1b with 
MMC_CMD_WRITE_MULTIPLE_BLOCK in mmc_rpmb_request:

+	cmd.cmdidx = MMC_CMD_WRITE_MULTIPLE_BLOCK;
+	cmd.cmdarg = 0;
+	cmd.resp_type = MMC_RSP_R1b;

Because according to the spec CMD25 has R1 response, also
RPMB section does not explicitly point on the response type,
maybe these words are the key:

"The busy signaling in the Dat0 line after the CRC status by the e•MMC 
is indicating request busy."

But I am not sure.
