[U-Boot] [PATCH 1/2] mmc: add boundary check for mmc operation

[Wolfgang Denk <wd@denx.de>]

Dear Lei Wen,

when posting new versions of patches, please always

1) make sure the messages are properly threaded, i. e. make sure to
   provide proper references to the previous postings;
   "git send-email" asks for the message ID.
2) show in the Subject that tthios is a new version of the patch (for
   example by using "[PATCH 1/2 v2]", and add (in the comment section,
   i. e. below the "---" line, a description of what was changed
   respective to the previous version(s).

Thanks.

puts() does not perform output formatting. You want printf() here (and
below).

Also, try to use a shorter message, for example:

	printf("MMC: block number 0x%x = %d exceeds max (0x%x = %d)", ...);


Best regards,
