[U-Boot] [PATCH 3/4] microblaze: enable LMB support

[Stephan Linz]

Foresighted to support flat device tree realocations we need to use
the new Logical memory blocks library in a manner as been used by all
other architectures.

First of all the flat device tree handling depends on CONFIG_SYS_BOOTMAPSZ. So 
I have to define a valid value. As far as I understand the initial memory map 
for Linux there have to be space for the kernel (text+data), fdt_blob and 
kernel parameters (at least). I'm unsure with an embedded init ramdisk as 
produced by simpleImage. The simpleImage can quickly grow up over 6MB with 
embedded initrd.

So I borrowed this configuration (8MB) from most other configurations (mainly 
PowerPC).

Stephan

ok. Microblaze handles FDT blob in different way. Kernel just need to 
know where it is and then is copied to another place.
We don't have any limits like 8MB or so that's why I prefer to setup 
~0UL value or something like that.

Can you please test it?

Thanks,
Michal

I see what you are trying to do but what
is your point with enabling LMB support ?

I am not sure if this enabling bring us any feature which we need.

Hm, mainly a clean compilation. Without this define I can not enable the flat 
device tree handling. LMB is quite new in U-Boot (PowerPC) and there are some 
dependencies to the FDT support. That force to enable even this feature on 
MicroBlaze too. I want to avoid a deep intrusion into the code.

Hm, could you pleace consult the PowerPC folks? I think LMB is used to 
transfer system memory map from U-Boot to Linux kernel in a common way 
(similar like on x86 PC from BIOS to kernel), or not? Any comments?

Stephan

I am not using the latest u-boot code - just checking if compilation is 
OK. But I can't see a reason why we should enable LMB because we don't 
need it. If there is any dependency then there are missing some ifdefs.

Stefan: How is LMB used in PowerPC? Microblaze uses LMB in kernel but 
IMHO we don't need to use it in u-boot and kernel is not ready for 
passing any memory map from U-BOOT. Maybe I am wrong that's why I would 
like to check this with you.

Thanks,
Michal

Hi Michal,

you are right. There are missing some ifdefs in the relocation code so there 
is no need to enable the LMB in U-Boot on Microblaze (also applies to the 8MB 
problem, CONFIG_SYS_BOOTMAPSZ).

Please be patient. I prepare a new patch set. I'll roll out as fast as 
possible ...

You're right. But I modified only a small pices and not the whole file.
