2017-07-11scsi: Move drivers into new drivers/scsi directorySimon Glass4-71/+1
At present we have the SCSI drivers in the drivers/block and common/ directories. It is better to split them out into their own place. Use drivers/scsi which is what Linux does. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2017-07-11sata: Move drivers into new drivers/ata directorySimon Glass21-9926/+1
At present we have the SATA and PATA drivers mixed up in the drivers/block directory. It is better to split them out into their own place. Use drivers/ata which is what Linux does. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2017-07-11Kconfig: Add CONFIG_SATA to enable SATASimon Glass1-0/+13
At present CONFIG_CMD_SATA enables the 'sata' command which also brings in SATA support. Some boards may wish to enable SATA without the command. Add a separate CONFIG to permit this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2017-07-11scsi: Drop scsi_print_error()Simon Glass2-9/+0
This function is only defined by one driver and is empty. Move it into the SCSI implementation itself. We could remove it, but it should be useful for debugging. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

There was for long time no activity in the 8xx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in 8xx, so remove it (with a heavy heart, knowing that I remove here the root of U-Boot). Signed-off-by: Heiko Schocher <hs@denx.de>
2017-06-09dm: blk: Add a way to obtain a block device from its parentSimon Glass1-0/+26
Many devices support a child block device (e.g. MMC, USB). Add a convenient way to get this device given the parent device. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2017-06-01dm: blk: Improve block device claimingSimon Glass1-3/+31
The intention with block devices is that the device number (devnum field in its descriptor) matches the alias of its parent device. For example, with: aliases { mmc0 = "/sdhci@700b0600"; mmc1 = "/sdhci@700b0400"; } we expect that the block devices for mmc0 and mmc1 would have device numbers of 0 and 1 respectively. Unfortunately this does not currently always happen. If there is another MMC device earlier in the driver model data structures its block device will be created first. It will therefore get device number 0 and mmc0 will therefore miss out. In this case the MMC device will have sequence number 0 but its block device will not. To avoid this, allow a device to request a device number and bump any existing device number that is using it. This all happens during the binding phase so it is safe to change these numbers around. This allows device numbers to match the aliases in all circumstances. Add a test to verify the behaviour. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: blk: Add a function to find the next block device numberSimon Glass1-6/+16
At present this code is inline. Move it into a function to allow it to be used elsewhere. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: blk: Allow finding block devices without probingSimon Glass1-2/+13
Sometimes it is useful to be able to find a block device without also probing it. Add a function for this as well as the associated test. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: core: Replace of_offset with accessor (part 2)Simon Glass1-3/+3
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: Rename dev_addr..() functionsSimon Glass2-3/+3
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-05-22Kconfig: Add a CONFIG_IDE optionSimon Glass4-1/+1241
At present IDE support is controlled by CONFIG_CMD_IDE. Add a separate CONFIG_IDE option so that IDE support can be enabled without requiring the 'ide' command. Update existing users and move the ide driver into drivers/block since it should not be in common/. Signed-off-by: Simon Glass <sjg@chromium.org>

2016-12-20dm: Add support for scsi/sata based devicesMichal Simek5-9/+64
All sata based drivers are bind and corresponding block device is created. Based on this find_scsi_device() is able to get back block device based on scsi_curr_dev pointer. intr_scsi() is commented now but it can be replaced by calling find_scsi_device() and scsi_scan(). scsi_dev_desc[] is commented out but common/scsi.c heavily depends on it. That's why CONFIG_SYS_SCSI_MAX_DEVICE is hardcoded to 1 and symbol is reassigned to a block description allocated by uclass. There is only one block description by device now but it doesn't need to be correct when more devices are present. scsi_bind() ensures corresponding block device creation. uclass post_probe (scsi_post_probe()) is doing low level init. SCSI/SATA DM based drivers requires to have 64bit base address as the first entry in platform data structure to setup mmio_base.
