[PATCH v3 00/18] i.MX serial cleanup, bootstrap code fixes, boot via IRAM

[Andrey Smirnov]

This patch set combines all previously sent patches together:

- Serial cleanups
- Bootstap code fixes/cleanup
- Boot via IRAM

I marked the whole thing as a version 3 since some of the included
patches in some of their incarnations had version 2 and I wanted to
decrease the amount of confusion I was creating :)

Andrey Smirnov (18):
  i.MX: Move UART definitions into a separate file
  i.MX: serial: Add constants for UART clock divisor
  i.MX: serial: Add baud rate calculation convenience functions
  i.MX: serial: Add UART init functions for DEBUG_LL
  i.MX: serial: Convert PUTC_LL to use IOMEM
  i.MX: serial: Convert i.MX51 and i.MX6 to use 'imx*_uart_setup_ll'
  i.MX51: babbage: Implement CONFIG_DEBUG_LL
  i.MX: serial: Distil common clock ungating code
  Makefile.lib: Make 'check_file_size' more flexible
  i.MX: Add provisions to boot from IRAM
  imx-image: Correctly fill image size in prepended header
  bootstrap: Fix potential memory leak in 'read_image_head'
  bootstrap_read_devfs(): Check for errors from devfs_add_partition()
  bootstrap_read_devfs(): Close file after we are done with it
  bootstrap_read_devfs(): Fix potential memory leak
  bootstrap_read_devfs(): Check for errors from dev_add_bb_dev()
  bootstrap_read_devfs(): Remove all partitions upon function completion
  bootstrap: Warn if image size in BB header is zero
