* mtd: nand: omap_gpmc: fix: remove bch4 string extantHeinrich.Toews@wago.com2018-05-311-1/+0
| | | | | | | | | | | Remove an erroneous bch4 string leftover that leads to a false ecc mode mapping. BCH4 support was previously removed by Teresa Remmet: d316cda 'mtd: nand: omap_gpmc: Remove BCH4 support' Signed-off-by: Heinrich Toews <heinrich.toews@wago.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd: nand: nand_omap_gpmc: Fix ecc stepsTeresa Remmet2018-05-241-60/+55
| | | | | | | | | | | | | | | | The eccsteps where set wrong for OMAP_ECC_BCH8_CODE_HW_ROMCODE. So the ECC was only corrected for the first 512 bytes chunk of a 2k page. Moved out the ecc step iteration out of the correcting loop to make it more alike the generic nand functions. And made sure that the ECC is caclulated for all chunks. This patch is based on work of Sascha Hauer. Fixes commit dec7b4d2bf9c ("mtd: nand_omap_gpmc: fix BCH error correction").

| * | serial: Drop .remove functions from all driversAndrey Smirnov2018-04-178-82/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Depending on specifics, some 'serdev' devices might need prevent parent console device from being removed and corresponding memory deallocated to properly function until the very end of Barebox's execution. An example of such a use-case would be a reset handler relying on a serdev device for transport. To avoid having to develop complicatione reference counting/ownership scheme drop all of the code that calls console_unregister() and frees the memory effectively making the problem above impossible to arise. All of the de-initialization that serial drivers were doing in their .remove functions was somewhat superflous anyway, so this change should be pretty harmless.

When this happens, the idle error count will read 0xFF after autonegotiation completes. Reset the PHY when in that state. is it possible that we get the link to late and barebox reports "Network is down". The problem is that ksz9031_config_init is called again in an error case.
