Issues with ColdFire toolchain

[Wolfgang Denk <wd@xxxxxxx>]

Hello,

we try to use the GCC-4.1 based toolchain for ColdFire to  build  the
U-Boot boot loader, the Linux kernel and some applications.

We ran into some problems:

(1) It seems that this configuration lacks  -fPIC  support  which  is
    crucial  for  U-Boot  building. [I am aware that -fpic support is
    present, but this is unfortunately not sufficient, too small  GOT
    size available.]

    Are there plans to support -fPIC ?

(2) We can build applications, but they don't run. For example,  when
    building OpenVPN we get:

	# ./openvpn
	Allocation of length 1136352 from process 46 failed
	DMA per-cpu: empty
	Normal per-cpu:
	cpu 0 hot: low 2, high 6, batch 1
	cpu 0 cold: low 0, high 2, batch 1
	HighMem per-cpu: empty

	Free pages:        5728kB (0kB HighMem)
	Active:571 inactive:1147 dirty:0 writeback:0 unstable:0 free:1432 slab:541 mapped:0
	pagetables:0
	DMA free:0kB min:0kB low:0kB high:0kB active:0kB inactive:0kB present:0kB

	pages_scanned:0 all_unreclaimable? no
	lowmem_reserve[]: 0 0 0
	DMA: empty
	Normal: 4*4kB 4*8kB 5*16kB 1*32kB 1*64kB 1*128kB 1*256kB 2*512kB 2*1024kB 1*2048kB
	0*4096kB = 5728kB
	HighMem: empty
	Unable to allocate RAM for process text/data, errno 12
	pid 46: failed 4

    Using the old uCLinux GCC-2.95 toolchain  this  works  fine.  For
    this working image, "file" reports

	openvpn: BFLT executable - version 4 gotpic

    Your GC-4.1 toolchain gives:

	openvpn: BFLT executable - version 4 ram

    Is this a problem? Any other idea what might be wrong?

Best regards,

Wolfgang Denk
