* Adapt the i.MX23 MCI driver to the v2 i.MX23 patch seriesJuergen Beisert2010-10-211-5/+5
| | | | | | | | | The i.MX23 v2 architecture patch series was sligthly modified to easify the i.MX28 architecture addition later on. So, we need now an index to query the SSP clock frequency. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Make the clock calculation easier to read and correctJuergen Beisert2010-10-211-7/+7
| | | | | | | | | | | Due to a wrong rounding while calculating the clock divider the requested clock of 25 MHz resulted into a 48 MHz clock. With this patch a clock frequency below or equal the requested one will be set. By using 'div' and 'rate' as vars, its also easier to check against the data sheet.

| * mci: align write buffer if necessarySascha Hauer2010-10-111-1/+15
| | | | | | | | | | | | | | | | | | | | Most SD controllers need some kind of alignment for writing blocks. Instead of coding this in every driver, align write blocks to a 4 byte alignment in the mci layer. For DMA accesses we may need bigger alignment, but let's solve this problem when we have it.

* Add S3C2440 MCI card supportJuergen Beisert2010-10-113-0/+825
| | | | | | | | | | Adding MCI card support for S3C2440 CPUs. This is for reference only, as there is currently no user in the barebox tree. Maybe one with access to the A9M2440 development kit can check it on his/her system. Checked here with my own S3C2440 based system which is not in the barebox tree.

| | | | | | | | | Adding MCI card support for STM378x/i.MX23 CPUs. This is for reference only, as this architecture is currently not part of barebox (but will coming soon).

* Don't try to guess the size of a disk if its size value is already givenJuergen Beisert2010-10-111-9/+18
| | | | | | | | | | | | | | | | | Guessing the size of an attached harddisk (access via x86 BIOS) was needed due to the fact, barebox can't query this information from the BIOS easily. But with the SD/MMC cards, there will be a second user of the generic disk handling routines. And with this media it is very easy to know its size. This patch provides a workaround to keep the guessing feature if the size of the registered disk is 0. If it is not 0, the given value will be used instead. Note: This is in preparation to add MCI card support, which can be handled like a disk drive. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Don't use a sector buffer on stackJuergen Beisert2010-10-111-5/+12
| | | | | | | | | | | | | | | Using a temp. buffer for a disk sector on the stack, seems not work. Doing so lets the system run crazy (the stack seems to be destroyd). Don't know the correct stack handling on ARM, but (IMHO) I also can exclude any writing across the buffer boundaries. Using a temp. buffer via malloc() runs also on ARM. Note: This patch was required to add MCI card support, which can be handled like a disk drive. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Make the disk driver less noisyJuergen Beisert2010-10-111-1/+2
| | | | | | | | | | | | In real life this output is only a "nice to have", but most of the time its useless and confusing. So, make it a debug feature for the interested developer. Note: This is in preparation to add MCI card support, which mostly come with a partition table and can be handled like a disk drive.

| | | | | | | | | | | Makes sure that the STOP condition is transmitted before the I2C controller is disabled. This fixes a problem where writing to an external EEPROM was not working because the EEPROM waits until the STOP before initiating the write internally.
