Move the errata handling mechanism from serial.c to omap-serial file and utilise the same func in driver file. Errata i202, i291 are moved to be handled with omap-serial Moving the errata macro from serial.c file to driver header file as from on errata will be handled in driver file itself. Corrected errata id from chapter reference 2.15 to errata id i291. Removed errata and dma_enabled feilds from omap_uart_state struct as they are no more needed with errata handling done within omap-serial.

This errata (i202) is applicable to all devices from OMAP2430 to OMAP4460 (apparently this one is not getting fixed). So could you make sure this is enabled for 2430, 3430, 3630, 4430 and 4460?

We should update the comment to be "Work Around for Errata i202 (2430, 3430, 3630, 4430 and 4460)". The "1.12" and "1.6" are just the section references in the errata docs, but I think that you can drop these as you can just search for the errata ID which is i202.
