This patch is required before the upcoming new enc28j60 driver using SPI framework patch can be applied: - Move legacy enc28j60.c to enc28j60_lpc2292.c. - Change Makefile and the two affected boards' definition files. Tested with ./MAKEALL ARM7 that both boards still compile. Signed-off-by: Reinhard Meyer<info@emk-elektronik.de> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
