* ARM: i.MX: bbu: Fix variable type in imx_bbu_internal_v2_write_nand_dbbt()Andrey Smirnov2019-03-111-1/+1
| | | | | | | | MEMGETBADBLOCK returns loff_t, so that's the type we should use to store its result. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | Don't use 'int' to store lseek()'s return value to avoid problems with large seek offsets. While at it, make sure to populate return error code from 'errno'. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: i.MX: bbu: Detect MMC before reading current boot partitionAndrey Smirnov2018-09-191-0/+6
| | | | | | | | | In order to be able to read "mmcN.boot" we need to detect that device first. Not doing so would result in failure if "barebox_update" is executed before "detect mmc0". Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX: bbu: Convert devicefile to device nameAndrey Smirnov2018-09-191-2/+3
| | | | | | | | Data->devicefile can contain absolute path to target device, so we need to convert it to a device name before we can safely use it. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | Convert imx_bbu_internal_v2_mmcboot_update() to use imx_bbu_update() for actual update in order to be able to support v1 as well as v2 headers. While at it rename the function to imx_bbu_internal_mmcboot_update() to reflect that change.

| | | | | | | | | Use pwrite_full() instead of pwrite() to make sure that all of the data was written to target device.

* ARM: i.MX: bbu: Adjust FLASH_HEADER_OFFSET_MMC for i.MX8MQAndrey Smirnov2018-08-311-6/+18
| | | | | | | | | | | | Flash header is located at 33KiB mark on i.MX8MQ, so we need to take that into account when initializing imx_handler->flash_header_offset. Convert FLASH_HEADER_OFFSET_MMC into a function call that will check if Barebox is running on i.MX8MQ CPU and adjust the offset accordingly.

| | | | | | | | | | Both code sections responsible for enabling/disabling underlying device write protection are almost identical to each other. To avoid code duplication move them into a separate routine and adjust the rest of the code accordignly.

* ARM: i.MX: bbu: Consolidate various update helpersAndrey Smirnov2018-08-311-58/+12
| | | | | | | | | | | All three, imx_bbu_internal_v1_update(), imx_bbu_external_update() and imx_bbu_internal_v2_update() are doing exactly the same thing. Instead of having three almost identical functions, convert imx_bbu_internal_v2_update() (the most versatile of the three) to be a generic function and use it everywhere.

* ARM: i.MX: bbu: Drop IMX_INTERNAL_FLAG_NANDAndrey Smirnov2018-08-311-10/+14
| | | | | | | | | | Replace IMX_INTERNAL_FLAG_NAND with a function pointer that can be customized by individual registration functions. The change by iteself doesn't have that much value, however it makes the simplification in the commit that follows more straightforward.

* ARM: i.MX: bbu: Move inner-image type checkAndrey Smirnov2018-08-311-25/+43
| | | | | | | | | | | | | | Since imx_bbu_check_prereq() already uses file_detect_type() and we've extended it to understand i.MX boot image file type, we can simplify a bunch of repetitive code as follows: 1. Convert all checks from IVT_BARKER to filetype_imx_image_v2 check 2. Move all of the checking to be a part of imx_bbu_check_prereq() Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: i.MX: bbu: support partitions starting at i.MX headerSascha Hauer2018-07-021-2/+5
| | | | | | | | The i.MX header is at an offset in the boot device, usually 0x400 bytes. This patch adds a flag to support the case that the partition the image is written to starts at that offset rather than 0x0. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX: bbu: reimplement IMX_INTERNAL_FLAG_KEEP_DOSPART flagSascha Hauer2018-07-021-45/+20
| | | | | | | | | | | | | | | | | | | This patch reimplements the IMX_INTERNAL_FLAG_KEEP_DOSPART flag and makes it more generic. Until now we only kept a dos partition table over the update. Beginning with i.MX8 we may also want to preserve a GPT, so we have to extend the preserved area. It might also be the case that not (only) a partition table is stored in the initial area of a device, but also other unrelated data, so it's better to just keep the initial area that is unused by the i.MX ROM. It's also good to export the flag to allow boards to specify the initial area shall be preserved. When a board wants to set the flag for a mtd like device then it has to check for suitable erase sizes beforehand. We do not check this (yet). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX: bbu: remove handler specific flags variableSascha Hauer2018-07-021-18/+17
| | | | | | | Now that we can store flags in the generic handler flags we no longer need our own variable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | This is a preparatory for the next patch that autodetects the device to write to. To not have to modify the callback data for each call, some static functions get an additional parameter to allow that. This doesn't affect boards making use of the file's function and doesn't change behaviour.
