Fix off-by-one error in passing initrd end address via device tree

2011-04-26T01:11:21+00:00

The initrd_end variable contains the address immediately *after* the
initrd blob, not the last address containing data.  This patch fixes
an inadvertent off-by-one when setting up the initrd reserved map.

fdt_support: Fix buffer overflow in fdt_fixup_memory_banks

2011-04-18T01:08:41+00:00

When fdt_fixup_memory_banks is called with 2-cell address and size
fields in the device-tree (IE: 64-bit address and size), then it will
overflow its on-stack "tmp" buffer.

This fixes the buffer size and adds a comment explaining how many bytes
need to be allocated per record.

common/fdt_support.c: Fix compile warnings

2010-10-20T06:59:16+00:00

Commit a6bd9e8 "FDT: Add fixup support for multiple banks of memory"
removed code but forgot to remove the variables used by it, resulting
in warnings:

fdt_support.c: In function 'fdt_fixup_memory_banks':
fdt_support.c:399: warning: unused variable 'sizecell'
fdt_support.c:399: warning: unused variable 'addrcell'

Remove the declarations, too.

FDT: Add fixup support for multiple banks of memory

2010-10-18T20:50:53+00:00

Add fdt_fixup_memory_banks and reimplement fdt_fixup_memory
using it.  Tested on OMAP3 beagle board with two banks of
memory.

fdt_support: support adding EDID property to FDT display nodes

2010-10-12T19:05:58+00:00

Boards can pass display timing info for drivers using EDID
block. Provide common function to add board specific EDID
data to the device tree. Subsequent patch makes use of this
functionality.

Detailed timing descriptor data from EDID is used for
programming the display controller. This is currently
implemented on the Linux side by the fsl-diu-fb frame
buffer driver and it is documented there in
Documentation/powerpc/dts-bindings/fsl/diu.txt.

ppc4xx/fdt/flash: Fix bug in fdt_fixup_nor_flash_node()

2010-10-04T09:19:49+00:00

This patch fixes a bug in fdt_fixup_nor_flash_node() when the reg
property has multiple reg tuples, like:

	reg = <0 0x00000000 0x04000000
	       0 0x04000000 0x04000000>;

In this case this function did not update the reg property correctly.

ppc4xx/fdt/flash: Change fdt_fixup_nor_flash_node() to not rely on cs size

2010-09-23T06:49:49+00:00

This patch changes the behaviour of the fdt_fixup_nor_flash_node()
function. Now it doesn't patch the size of the "reg" property with the
chip-select size, but with the size returned from the new function
flash_get_bank_size(). This function will return per weak default the
flash size of the bank (bank = chip-select numer) detected by the flash
driver. If this does not fit your needs, this function may be overridden
by a board specific one.

For this the parameters needed to be changed. So I intentionally squashed
the PPC4xx stuff using this routine into this patch. Otherwise it would
not be git-bisectable anymore.

The board specific function for the AMCC/APM Ebony eval board is now
included in this patch version.

fdt: call fdt_parent_offset fewer times while translating addresses

2010-08-20T02:21:41+00:00

fdt_parent_offset() is an expensive operation, so we'd like to reduce
unnecessary calls to it.

Further, the practice of iterating up to the root if address/size cells
aren't found was apparently done for Linux for compatibility with certain
buggy Open Firmware implementations, and U-Boot inherited the code.  The
compliant behavior is to treat a missing #address-cells as 2, and a missing
#size-cells as 1 -- never looking anywhere but the immediate parent of the
node of interest.
