           Summary: STM32 flash driver support for non-aligned source
                    buffers.
           Product: eCos
           Version: CVS
          Platform: stm32e_eval (ST STM3210E EVAL board)
        OS/Version: Cortex-M
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: low
         Component: Flash
        AssignedTo: unassigned@bugs.ecos.sourceware.org
        ReportedBy: chris@zynaptic.com
                CC: ecos-bugs@ecos.sourceware.org

Patch to support non-aligned source buffers for STM32 flash.

The current CVS version of the STM32 flash driver requires the source buffer to
be 16-bit aligned for writes.  This causes problems when attempting to program
the flash from data held in non-aligned buffers.  I am currently using the
attached patch to work around this.

In addition the patched version checks that the length of the write data is an
integer number of flash words, rather than silently discarding the last byte
when an odd number of bytes is written.
