MMC: add weak function to detect MMC/SD card 2010-03-07T18:36:36+00:00 Stefano Babic sbabic@denx.de 2010-02-05T14:04:43+00:00 11fdade294b4d60c19ae861515aabddca1278deb Most controllers can check if there is a card in the slot. However, they require pins that could be not available because required by other functions and the detection of a card must be performed in another way. This patch adds a weak function that a board can implement to add its internal custom way to check the presence of a MMC/SD card. Signed-off-by: Stefano Babic <sbabic@denx.de>

mmc: fix response decoding on little endian 2009-06-02T22:18:57+00:00 Rabin Vincent rabin@rab.in 2009-04-05T08:00:55+00:00 0b453ffe28bb9227d86ddbe0893bd19c93f04ed7 The mmc code defines the response as an array of chars. However, it access the response bytes both as (i) an array of four uints (with casts) and (ii) as individual chars. The former case is used more often, including by the driver when it assigns the response. The char-wise accesses are broken on little endian systems because they assume that the bytes in the uints are in big endian byte order. This patch fixes this by changing the response to be an array of four uints and replacing the char-wise accesses with equivalent uint-wise accesses. Signed-off-by: Rabin Vincent <rabin@rab.in>

Add MMC Framework 2009-02-17T00:07:41+00:00 Andy Fleming afleming@freescale.com 2008-10-30T21:41:01+00:00 272cc70b211e945e4413122aa73868f6ada732a5 Here's a new framework (based roughly off the linux one) for managing MMC controllers. It handles all of the standard SD/MMC transactions, leaving the host drivers to implement only what is necessary to deal with their specific hardware. This also hooks the infrastructure into the PowerPC board code (similar to how the ethernet infrastructure now hooks in) Some of this code was contributed by Dave Liu <daveliu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

Eliminated arch-specific mmc header requirement 2009-02-17T00:07:41+00:00 Andy Fleming afleming@freescale.com 2008-10-30T21:31:39+00:00 1de97f9856f697380cc504126ab92561ed238803 The current MMC infrastructure relies on the existence of an arch-specific header file. This isn't necessary, and a couple drivers were forced to implement dummy files to meet this requirement. Instead, we move the stuff in those header files into a more appropriate place, and eliminate the stubs and the #include of asm/arch/mmc.h Signed-off-by: Andy Fleming <afleming@freescale.com>

MMC: Consolidate MMC/SD command definitions 2008-06-28T20:40:15+00:00 Haavard Skinnemoen haavard.skinnemoen@atmel.com 2008-05-22T09:09:59+00:00 341188b9ccaa8d4462d772cc067aca8d7618633a This moves the MMC and SD Card command definitions from include/asm/arch/mmc.h into include/mmc.h. These definitions are given by the MMC and SD Card standards, not by any particular architecture. There's a lot more room for consolidation in the MMC drivers which I'm hoping to get done eventually, but this patch is a start. Compile-tested for all avr32 boards as well as lpc2292sodimm and lubbock. This should cover all three mmc drivers in the tree. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
