2008-07-25[MTD] physmap: resume already suspended chips on failure to suspendUwe Kleine-König
A nice side effect of this patch is that the return value of physmap_flash_suspend in the error path is the value of the first failing suspend callback and not the bitwise OR of all of them.

2008-04-22[MTD] [MAPS] fix platform driver hotplug/coldplugKay Sievers
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable MTD mapping platform drivers, to re-enable auto loading. NOTE oddness with physmap ... it's a legacy driver in some configs, which means it can't always support hotplugging. (Not that most of these mapping drivers would often be used as modules...)

2008-02-03[MTD] physmap.c: Add support for multiple resourcesStefan Roese
This patch extends the physmap mapping driver to support multiple resources for non-identical NOR chips that will be concatenated together when selected. This is needed for example for Intel 48F4400 512MBit chips, since they consist of 2 single different NOR chips with different geometries. The first (lower) one has botton boot sectors and the 2nd (upper) has top boot sectors. This currently isn't handled correctly by calling the physmap driver once with only one resource covering both chips in one memory region. The same geometrie is used for both chips. With this patch the following resource structure can be used to describe the 48F4400 chip correctly: static struct resource board_nor_resource[] = { [0] = { .start = 0xf8000000, .end = 0xfbffffff, .flags = IORESOURCE_MEM, }, [1] = { .start = 0xfc000000, .end = 0xffffffff, .flags = IORESOURCE_MEM, } }; Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2006-05-07[MTD] Convert physmap to platform driverLennert Buytenhek
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.)

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
