Milestone Port eCos + MRG to BlackFin Stamp-537 development board

Do as much as we can of porting eCos + MRG to the Blackfin Stamp. Currently done:

• eCos port by Chemnitz extended/refactored/fixed 2 buglets
• added GPIO module to eCos/Blackfin
• refactored MRG so it supports multiple eCos architectures better
• added MRG interfaces for eCos/Blackfin: timer, GPIO, ...
• first step for getting U-Boot into the STAMP is to rebuild U-Boot, load it over Ethernet and test-run it in the standard application-upload manner
• eCos JFFS2 cannot run on NAND flash; decided to create an eCos NAND Flash package and port YAFFS
• have a look if we can use the BF to generate modulated signal using its timers: OK, even for 14443A
• upload rebuilt U-Boot and burn it into the Flash in the standard application-upload manner.
• we will aim at using the serial port to do the initial pre-boot booting and try to skip JTAG altogether (obsolete> start to try and load U-Boot over JTAG into Stamp-537's flash; involves) (obsolete> - getting UrJtag to speak to BFin) (obsolete> - getting UrJtag to speak to our Flash) (obsolete> - build U-Boot for the Stamp-537 (done)) (obsolete> - get the boot address, reset etc right)

ToDo:

• do as much as we can with the Ethernet on Stamp
• talk to Andre Liesk (Chemnitz) about interrupt model
• have a look if the second UART can be configured, and can speak to the LinkMatic BlueTooth module
