It now accepts: Ki, Mi, Gi - the official prefixes for binary multiples, see http://physics.nist.gov/cuu/Units/binary.html, ki - mistake on my side and analog to "k" for decimal multiples, KiB, MiB, GiB - for people that prefer to add a "B" for byte, kiB - combination of the above. There were complaints about not accepting "k" for 1024. This has long been common practice, but is known to lead to confusion. Hence the new SI units and hence block2mtd only accepts units that cannot be confused with decimal units. Diverging from common practice doesn't always please people, even if the change is for the better.

-- cgit v1.2.3-18-g5258 From 73566edf9b91dd085ddb12033d0ea7288979dd10 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Sun, 7 May 2006 17:16:36 +0100 Subject: [MTD] Convert physmap to platform driver After dwmw2 let me know it ought to be done, I rewrote the physmap map driver to be a platform driver. I know zilch about the driver model, so I probably botched it in some way, but I've done some tests on an ixp23xx board which uses physmap, and it all seems to work. In order to not break existing physmap users, I've added some compat code that will instantiate a platform device iff CONFIG_MTD_PHYSMAP_LEN is defined and != 0. Also, I've changed the default value for CONFIG_MTD_PHYSMAP_LEN to zero, so that people who inadvertently compile in physmap (or new, platform-style, users of physmap) don't get burned. This works pretty well -- the new physmap driver is a drop-in replacement for the old one, and works on said ixp23xx board without any code changes needed. (This should hold as long as users don't touch 'physmap_map' directly.) Once all physmap users have been converted to instantiate their own platform devices, the compat code can go. (Or we decide that we can change all the in-tree users at the same time, and never merge the compat code.)
