[PATCH 00/11] archosg9: add support for tablet, third round

[vj]

Hello,
 here is the third round of patches including most of the modifications suggested by your comments, which are greatly appreciated.
 one of the modifications not done is the move of the usb-booting infrastructure into a driver. Jean, can you please add more information about this? Thanks.
 
 scripts/checkpatch.pl returns two errors: "Macros with complex values should be enclosed in parenthesis", but in this case parenthesis can't be added, any suggestion?
 
 This new round of patches applies against 026e6aeb8206accdbef88408ae8c6c8bffcdc212 which includes a lots of changes.
 The change 29e4031b460d1c84c1a8fc276199d40680b354d4 "ARM OMAP: switch to gpiolib support" breaks support for the tablet and it's reverted here only to make this patch-list feature-complete.
 Can somebody check if gpiolib works for other OMAP4460-based boards?
 
 About the default serial speed: it's set to 1Mbaud to match the rate of the factory bootloader, this way we can see all the messages printed.
 Before it was set to 57600 because it was the highest speed that worked with linux because of serial port auto-suspend. It was nothing to do with barebox.

 The patch-list adds a regression fix added at faf7b7af6e51a33b88453821d792c89a84f72b1d "ARM: give boards control of the reset entry point"
 
 Regards,
  Vicente.
