powerpc: remove 4xx support

2017-07-03T21:35:28+00:00

There was for long time no activity in the 4xx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 4xx,
so remove it.

fdt: Rename a few functions in fdt_support

2017-06-01T13:03:11+00:00

These two functions have an of_ prefix which conflicts with naming used
in of_addr. Rename them:

   fdt_read_number
   fdt_support_bus_default_count_cells

fdt: Update fdt_get_base_address() to use const

2017-06-01T13:03:07+00:00

This function does not change the device tree so adjust it to use const
for this parameter.

fdt_support: Fixup 'ethernet' aliases not ending in digits

2017-03-26T14:58:23+00:00

The Raspberry Pi device tree files since Linux v4.9 have a "ethernet"
alias pointing to the on-board Ethernet device node. However,
U-Boot's fdt_fixup_ethernet() only looks at ethernet aliases ending
in digits.

As the spec doesn't mandate that aliases must end in numbers and there
have been much older uses of an "ethernet" aliases in the wild
(according to Tom Rini), change the code to accept "ethernet" as well.

Without this Linux isn't told of the MAC address provided by the
RPI firmware and the ethernet interface is always assigned a random MAC
address.

common: fdt_support: Remove check for mtdparts in fdt_fixup_mtdparts

2017-02-08T12:34:52+00:00

fdt_fixup_mtdparts currently does nothing when partition info is
runtime-generated or compiled-in defaults are used.

net: cosmetic: Do not use magic values for ARP_HLEN

2017-02-07T16:54:32+00:00

Commit 674bb249825a ("net: cosmetic: Replace magic numbers in arp.c with
constants") introduced a nice define to replace the magic value 6 for
the ethernet hardware address. Replace more hardcoded instances of 6
which really reference the ARP_HLEN (iow the MAC/Hardware/Ethernet
address).

libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORY

2016-12-03T03:54:34+00:00

Commit e2f88dfd2d96 ("libfdt: Introduce new ARCH_FIXUP_FDT option")
allows us to skip memory setup of DTB, but a problem for ARM is that
spin_table_update_dt() and psci_update_dt() are skipped as well if
CONFIG_ARCH_FIXUP_FDT is disabled.

This commit allows us to skip only fdt_fixup_memory_banks() instead
of the whole of arch_fixup_fdt().  It will be useful when we want to
use a memory node from a kernel DTB as is, but need some fixups for
Spin-Table/PSCI.

cmd/fdt: add possibilty to have 'extrasize' on fdt resize

2016-10-13T19:54:10+00:00

Sometimes devicetree nodes and or properties are added out of the u-boot
console, maybe through some script or manual interaction.

The devicetree as loaded or embedded is quite small, so the devicetree
has to be resized to take up those new nodes/properties.

In original the devicetree was only extended by effective
4 * add_mem_rsv.

With this commit we can add an argument to the "fdt resize" command,
which takes the extrasize to be added.

fdt_support: fdt_translate_address() blob const correctness

2016-08-12T15:20:27+00:00

The next patch will call fdt_translate_address() from somewhere with a
"const void *blob" rather than a "void *blob", so fdt_translate_address()
must accept a const pointer too. Constify the minimum number of function
parameters to achieve this.
