* ARM: i.MX: add i.MX8MN (Nano) SoC support boilerplateAhmad Fatoum2021-10-051-4/+4
| | | | | | | | | The Nano is basically a downsized mini. Add the necessary bits, so driver and board support can be added.

* ARM: i.MX8MP: bbu: fix wrong flash header offset for eMMC boot partitionAhmad Fatoum2021-10-051-1/+16
| | | | | | | | | | | | | | According to the reference manual of the i.MX8MP, the bootrom expects the bootloader to sit directly at the start of the eMMC boot partition. The 32K offset is only valid for eMMC user partitions and SD. Tell barebox_update about this, so it can strip away the first 32K when writing to an eMMC boot partition.

* ARM: i.MX8M: bbu: rename imx8mq_bbu_* functions to imx8m_bbu_*Ahmad Fatoum2020-12-071-3/+3
| | | | | | | | | | | imx_bbu_internal_mmcboot_register_handler already supports the i.MX8MQ, i.MX8MP and i.MX8MM, but the latter two do not have helpers with their SoC as prefix. As it seems like that it will be possible to extend imx_bbu_internal_mmcboot_register_handler for upcoming SoCs in the i.MX8M family as well, rename the function to start with imx8m_.

* ARM: i.MX: bbu: early exit when partition too smallAhmad Fatoum2019-08-301-0/+10
| | | | | | | | | | | | | | | | | | | | So far, writing a barebox image exceeding the partition size aborts with EPERM as truncate isn't implemented: ERROR: writing to /dev/flash-boot.barebox failed with Operation not permitted update failed ERROR: fastboot: update barebox: Operation not permitted This is unfortunate because by the time the truncation fails, erasing the partition had already occurred. Avoid this by checking prior to the pwrite_all whether the file to be written is big enough. This is valid here because barebox update wouldn't be called on a regular file. While at it, present callers with a more helpful ENOSPC error. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> 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>
