* env_mmc: support overriding mmc dev from board codeClemens Gruber2016-01-25-7/+12
| | | | | | | | | | | | | | | | | | | | | | | This enables boards to choose where to/from the environment should be saved/loaded. They can then for example support using the same device (dynamically) from which the bootloader was launched to load and save env data and do not have to define CONFIG_SYS_MMC_ENV_DEV statically. In my use case, the environment needs to be on the same device I booted from. It can be the eMMC or an optional SD card. I therefore would override mmc_get_env_dev in the board code, read the CPU registers to determine where we booted from and return the corresponding device index.

* mmc: store hwpart in the block deviceStephen Warren2016-01-13-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will allow us to have multiple block device structs each referring to the same eMMC device, yet different HW partitions. For now, there is still a single block device per eMMC device. As before, this block device always accesses whichever HW partition was most recently selected. Clients wishing to make use of multiple block devices referring to different HW partitions can simply take a copy of this block device once it points at the correct HW partition, and use each one as they wish. This feature will be used by the next patch. In the future, perhaps get_device() could be enhanced to return a dynamically allocated block device struct, to avoid the client needing to copy it in order to maintain multiple block devices. However, this would require all users to be updated to free those block device structs at some point, which is rather a large change. Most callers of mmc_switch_part() wish to permanently switch the default MMC block device's HW partition. Enhance mmc_switch_part() so that it does this. This removes the need for callers to do this. However, common/env_mmc.c needs to save and restore the current HW partition. Make it do this more explicitly. Replace use of mmc_switch_part() with mmc_select_hwpart() in order to remove duplicate code that skips the call if that HW partition is already selected.

* block: pass block dev not num to read/write/erase()Stephen Warren2016-01-13-7/+3
| | | | | | | | | | | This will allow the implementation to make use of data in the block_dev structure beyond the base device number. This will be useful so that eMMC block devices can encompass the HW partition ID rather than treating this out-of-band. Equally, the existence of the priv field is crying out for this patch to exist.

* env_mmc: Properly prefix mmc errors with '!'Hans de Goede2015-08-28-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | The set_default_env() function from env_common.c expects either a fully formatted error msg, e.g.: "## Resetting to default environment\n" or an error msg prefixed with an !, in which case it will format it. Fix the init_mmc_for_env() error messages to be prefixed with a ! this changes the bootup-log on sunxi when no mmc card is found from: MMC: SUNXI SD/MMC: 0 No MMC card foundIn: serial Out: serial To: MMC: SUNXI SD/MMC: 0 *** Warning - No MMC card found, using default environment In: serial Out: serial Which clearly is how things should look.

* env_mmc: allow negative CONFIG_ENV_OFFSETStephen Warren2013-06-13-2/+10
| | | | | | | | | | | | | | | | A negative value of CONFIG_ENV_OFFSET is treated as a backwards offset from the end of the eMMC device/partition, rather than a forwards offset from the start. This is useful when a single board may be stuffed with different eMMC devices, each of which has a different capacity, and you always want the environment to be stored at the very end of the device (or eMMC boot partition for example). One example of this case is NVIDIA's Ventana reference board. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

* env_mmc: allow environment to be in an eMMC partitionStephen Warren2012-09-05-8/+56
| | | | | | | | | | | | | eMMC devices may have hardware-level partitions: 2 boot partitions, up to 4 general partitions, plus the user area. This change introduces optional config variable CONFIG_SYS_MMC_ENV_PART to indicate which partition the environment should be stored in: 0=user, 1=boot0, 2=boot1, 4..7=general0..3. This allows the environment to be kept out of the user area, which simplifies the management of OS-/user-level (MBR/GPT) partitions within the user area.
