Subject: [U-Boot] Remove board specific code from ENC28J60 network driver?
Date: Sun, 20 Dec 2009 20:30:35 +0100 [thread overview]
Message-ID: <4B2E7B5B.3050603@googlemail.com> (raw)
For TI OMAP3 Beagle based Zippy expansion board from TinCanTools [1]
I'm currently looking into reusing spi based ENC28J60 network driver
drivers/net/enc28j60.c
It seems to me that it uses LPC2292 specific macros
IO1CLR, IO1SET and IO1DIR
These macros are defined in
asm-arm/arch-lpc2292/lpc2292_registers.h
From enc28j60.c:
...
#define enc_enable() PUT32(IO1CLR, ENC_SPI_SLAVE_CS)
#define enc_disable() PUT32(IO1SET, ENC_SPI_SLAVE_CS)
...
...
/* configure GPIO */
(*((volatile unsigned long *) IO1DIR)) |= ENC_SPI_SLAVE_CS;
(*((volatile unsigned long *) IO1DIR)) |= ENC_RESET;
/* CS and RESET active low */
PUT32 (IO1SET, ENC_SPI_SLAVE_CS);
PUT32 (IO1SET, ENC_RESET);
...
Anybody with an idea how to move this code to some (LPC2292?) board
specific files to make enc28j60.c more generic to be able to reuse it
on other boards?
Best regards
Dirk
