OK. Take a look at:
packages\hal\arm\arch\current\src\redboot_linux_exec.c
There are directly used "CYGMEM_REGION_ram_SIZE" define:
#ifndef CYGHWR_REDBOOT_LINUX_ATAG_MEM
#define CYGHWR_REDBOOT_LINUX_ATAG_MEM(_p_) \
CYG_MACRO_START \
/* Next ATAG_MEM. */ \
_p_->hdr.size = (sizeof(struct tag_mem32) + sizeof(struct tag_header))/sizeof(long); \
_p_->hdr.tag = ATAG_MEM; \
/* Round up so there's only one bit set in the memory size. \
* Don't double it if it's already a power of two, though. \
*/ \
_p_->u.mem.size = 1<<hal_msbindex(CYGMEM_REGION_ram_SIZE); \
if (_p_->u.mem.size < CYGMEM_REGION_ram_SIZE) \
_p_->u.mem.size <<= 1; \
_p_->u.mem.start = CYGARC_PHYSICAL_ADDRESS(CYGMEM_REGION_ram); \
CYG_MACRO_END
#endif
And in do exec:
// Fill in the details of the memory layout
CYGHWR_REDBOOT_LINUX_ATAG_MEM(params);
So you can diag_printf "CYGMEM_REGION_ram_SIZE" before call to this macro and see
If there are right value. If not - look for what is wrong.

I just dug into this today...I put a dump in redboot_linux_exec.c after
filling up the ATAGs and before executing kernel and looked at memory at
0x100. It looks perfect to me...ATAGs present are ATAG_CORE, ATAG_MEM and
ATAG_CMDLINE.
Just so I am sure I am not missing anything to modify...my understanding of
what needs to be changed to accomodate ONLY an SDRAM configuration and size
change from a 256MB IXDP425 to a 32MB IXDP425 is:
ixdp425/current/include/ixdp425.h
#define SDRAM_SIZE 0x02000000
#define IXP425_SDRAM_CONFIG_INIT (SDRAM_CONFIG_CAS_3 |
SDRAM_CONFIG_2x16Mx16)
ixdp425/current/include/pkgconf/mlt_arm_xscale_ixdp425_rom.ldi
ram : ORIGIN = 0, LENGTH = 0x02000000
ixdp425/current/include/pkgconf/mlt_arm_xscale_ixdp425_rom.h
#define CYGMEM_REGION_ram_SIZE (0x02000000)
#define CYGMEM_SECTION_heap1_SIZE (0x02000000 - (size_t) CYG_LABEL_NAME
(__heap1))
ixdp425/current/include/pkgconf/mlt_arm_xscale_ixdp425_rom.h
region ram 0 02000000 0 !
And just to be sure...I took previous advise and modified the ram mlt files
as well.
Is there something I am missing that needs to be modified?
Thanks!
-Dave

Dump the value of
CYGARC_PHYSICAL_ADDRESS(CYGHWR_REDBOOT_ARM_LINUX_TAGS_ADDRESS)
This is the value that should be in your linux's machine_desc.boot_params

CYGARC_PHYSICAL_ADDRESS(CYGHWR_REDBOOT_ARM_LINUX_TAGS_ADDRESS)
0x100
arch/arm/mach-ixp425/arch.c
#ifdef CONFIG_ARCH_IXDP425
...
BOOT_PARAMS(0x0100)
Is there another location I should be looking in the kernel for
machine_desc.boot_params?
Thanks!

Hello all,
Following up on the issue I originally reported. I dug into the issue more
and I just cannot see anything that I am missing. The memory looks correct
between a working 64mb configuration and a 32mb configuration...however
ATAGS are still not usable on the 32mb configuration.
The issue as originally reported is that I have a 64mb IXDP425 board with
RedBoot 2.01 which works fine with a 2.4.27 kernel. ATAGS work correctly, I
can override the kernel command line just fine via exec -c "". I have a 32mb
IXDP425 board with the same RedBoot 2.01 except that changes have been made
to reflect the SDRAM memory layout and size. Also adjusted are the mlt files
in pkgconf/. The ATAGS on the 32mb board look fine in memory after calling
exec -c "" however the 2.4.27 kernel thinks they are somewhere else than on
the 64mb board. The kernel being used is identical for both the 32mb and
64mb boards.
I placed a memory dump in redboot after exec but before kernel exec and the
ATAGS can be seen just fine on both 32 and 64. I also placed some printks in
the kernel to show ATAG stuff and it is different between the 64/32.
The changes made to the RedBoot source as well as the memory dump and kernel
printks I placed at:
http://ixp.cc0.net/
To save forwarding all this info to the mailing list.
Anyone have an idea what I am missing that needs to be changed?
Thanks!
-Dave

Your cmdline tells your kernel that you have 64MB on the 32MB
board. The mem= line shouldn't be needed as the kernel gets it from
ATAG_MEM (if it works atleast).
Could you dump the mdesc->param_offset memory in the kernel to see if
it's the same as in RedBoot?

The offset is in the dumps at http://ixp.cc0.net
It is during the kernel boot there are a bunch of printk's and param_offset
is one of them. It is at 0x100 which is same as RedBoot.
I know that the command line is offering a different mem value..that is what
I am using to test if ATAGs are working or not. I should see the command
line in the kernel if they are working.

Yes, but could you dump the memory around 0x100 in the kernel as well?
It should be the same as the dump in RedBoot, but apparently it isn't.

Probably so...
The only RB differences between the 64MB that does work and the 32MB that
does not work is the following:
ixdp425.h:
#define SDRAM_SIZE 0x02000000
#define IXP425_SDRAM_CONFIG_INIT (SDRAM_CONFIG_CAS_3 |
SDRAM_CONFIG_2x8Mx16)
mlt_arm_xscale_ixdp425_ram.h:
#define CYGMEM_REGION_ram_SIZE (0x02000000)
#define CYGMEM_SECTION_heap1_SIZE (0x02000000 - (size_t) CYG_LABEL_NAME
(__heap1))
mlt_arm_xscale_ixdp425_rom.h:
#define CYGMEM_REGION_ram_SIZE (0x02000000)
#define CYGMEM_SECTION_heap1_SIZE (0x02000000 - (size_t) CYG_LABEL_NAME
(__heap1))
mlt_arm_xscale_ixdp425_rom.ldi:
ram : ORIGIN = 0, LENGTH = 0x02000000

It did not resolve the issue. I changed it to reflect 32MB however ATAGs are
still not passed to kernel.
