common: Fix-up MAC addr in dts by fetching env variable serially

2017-12-24T19:42:50+00:00

The MAC addresses get fixed in the device tree for "ethernet" nodes
is by using trailing number behind "ethernet" found in "/aliases".
It may not be necessary for the "ethernet" nodes to be sequential.
There can be gaps in between or any node disabled

So provide a support to fetch MAC addr sequentially from env
and apply them to "ethernet" nodes in the order they appear in
device tree only if "ethernet" is not "disabled"

spl: fit: implement fdt_record_loadable

2017-11-25T23:39:07+00:00

During the loading of more complex FIT images (e.g. when the invoked
next stage needs to find additional firmware for a power-management
core... or if there are multiple images for different privilege levels
started in parallel), it is helpful to create a record of what images
are loaded where: if a FDT is loaded for one of the next stages, it
can be used to convey the status and location of loadables.

This adds a fdt_record_loadable() function that can be invoked to
record the status of each loadable below the /fit-images path.

fdt: Introduce helper method fdt_overlay_apply_verbose()

2017-09-15T11:27:48+00:00

Introduce fdt_overlay_apply_verbose, a method that applies an
overlay but in the case of an error produces a helpful message.

In addition if a base tree is found to be missing the __symbols__
node the message will point out that the probable reason is that
the base tree was miscompiled without the -@ option.

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24+00:00

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

fdt: Correct fdt_get_base_address()

2017-08-01T02:58:00+00:00

This function appears to obtain the value of the 'ranges' property rather
than 'reg'. As such it does not behave as documented or expected.

In addition it picks up the second field of the property which is the size
(with prop += naddr) rather than the first which is the address.

Fix it.

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.
