* | imx nand: move initialization to preset functionSascha Hauer2010-11-121-39/+71
| | | | | | | | | | | | | | | | | | This has two purposes. First we need to factor out initialization to be able to do something different on v3 type controllers, second with this patch we are independent of preinitialized register values. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | mxc_nand: fix correct_data functionSascha Hauer2010-11-121-2/+42
| | | | | | | | | | | | | | | | | | The v2 controller has a totally different mechanism to check whether the data we read had ecc errors or not. Implement this. The mechanism in the v2 controller happens to be identical to the v3 controller. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | imx nand: add V1_V2 namespace to registersSascha Hauer2010-11-121-134/+86
| | | | | | | | | | | | | | | | | | This prepares the driver for v3 support. The v3 controller has a completely different register layout, so add a V1_V2_ namespace to the register defines to avoid confusion with the v3 regs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | imx_nand: make some internally used functions overwriteableSascha Hauer2010-11-121-26/+40
| | | | | | | | | | | | | | | | This patch prepares the driver to add v3 controller support later. The v3 controller is basically the same controller as v1 and v2, but with a completely different register layout. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | imx nand: remove unnecessary register writeSascha Hauer2010-11-121-12/+1
| | | | | | | | | | | | | | NFC_SP_EN is cleared in probe and never set again, so we do not need to clear it in other functions again. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | imx_nand: rework get_dev_statusSascha Hauer2010-11-121-11/+10
| | | | | | | | | | | | | | | | | | | | We save/restore the value in the buffer anyway, so it makes no difference whether we use main_area0 or main_area1. So, we can use main_area0 and remove main_area1 from the driver which is otherwise unused. Also, clean up the comments in get_dev_status. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | imx_nand: remove 0xe00 offset from registersSascha Hauer2010-11-121-21/+21

* mci: align data for commandsSascha Hauer2010-10-221-6/+6
| | | | | | | | | | | Some mci controllers cannot transfer data with their DMA engines if the data is not sufficiently aligned. Normally this is a driver problem, but hey, we have no problem aligning the data and keep the burden from the drivers.

* fb: i.MX IPU: move fb_info initialization to a single functionSascha Hauer2010-10-221-28/+35
| | | | | | | | | | The bitfield information was only added to fb_info when the framebuffer actually was enabled. That made it impossible to call 'bmp' before enabling the display. So, move all fb_info init to a single place and make it a function to better allow for multiple displays later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* 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.

* 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>

| | | | | | | | | | | | 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.
