[U-Boot-Users] U-boot ColdFire development

[Liew Tsi Chung-r5aahp]

Stefan,

	I made some update on the 5329. We need to get started on
migrating the mcf52x2 as soon as possible.

1. Files that use <asm/immap_5329.h> and <asm/m5329.h> were replaced to
<asm/immap.h>.
2. CPU/ARCH specific defines are placed in include/asm/immap.h
3. drivers/serial/mcfserial.c renamed to drivers/serial/mcfuart.c. I
want to keep it that way so that it won't mix up with other uarts
drivers.
4. rtc/rtc.c renamed to rtc/mcfrtc.c, same reason as no. 3
5. cache_enable() moved from cpu_init_r() to cpu_init_f() for fast
allocation
6. used generic cfi driver
7. Will keep the cpu folder for each family. Certain CPU has different
cache and speed configuration.
8. MII will still be placed in board/xxxx/mii.c

Stefan,

Here is the test version for 5329 u-boot source at Freescale.
http://opensource.freescale.com/git?p=u-boot-coldfire.git;a=summary

Added:
board/freescale/M5329EVB/Makefile config.mk flash.c m5329evb.c and
u-boot.lds cpu/mcf532x/Makefile config.mk cpu.c cpu_init.c speed.c
start.S drivers/net/mcffec.c drivers/serial/mcfserial.c
include/asm-m68k/immap_5329.h m5329.h mcfrtc.h
include/configs/M5329EVB.h lib_m68k/interrupts.c rtc/rtc.c

Modified:
Makefile
MAKEALL
README
common/cmd_bdinfo.c cmd_mii.c
include/asm-m68k/byteorder.h fec.h io.h mcftimer.h mcfuart.h ptrace.h
u-boot.h lib_m68k/board.c time.c

I had placed the mcfserial.c under drivers/serial and mcffec.c under
drivers/net. The rtc.c is under rtc/.

1. I do have one more doubt about placing the following defines as we
discussed early.

> /* Timer */
> #define CONFIG_MCFTMR
> #ifdef CONFIG_MCFTMR
> #	define CFG_UDELAY_BASE	(0xFC070000)
> #	define CFG_TMR_BASE		(0xFC074000)
> #	define CFG_INTR_BASE	(0xFC048000)
> #	define CFG_TMRINTR_NO	(32)
> #	define CFG_TMRINTR_MASK	(1)
> #endif

If I place the #ifdef CONFIG_MCFTMR ... #endif in say immap_5329.h,
isn't that in time.c must include <asm/immap_5329.h>.

Time.c
#ifdef CONFIG_5329
#include <asm/immap_5329.h>
#endif

#ifdef CONFIG_5272
#include <asm/immap_5272.h>
#endif
...

Is there a way not to include <asm/immap_5xxx.h> in time.c each time a
new processor is added?

2. I seperated the MII feature from fec.c and placed in under
board/freescale/mxxxevb.c. Since the mii phy is board dependent not cpu
dependent, do you agree?

3. EHCI/OTG driver development. Do I need to modify the current
cmd_usb.c to include EHCI or create a new file cmd_hsusb.c?
