When the "w1 bus" command is used with no bus master present
a data abort may occur.

This is because uclass_first_device() returns zero, but sets the output
struct udevice pointer to NULL in the no device found case.

Fix w1_get_bus() to account for this and return an error code
as is expected by the callers.

Data abort was occurring when using "w1 bus" with a DS24B33 present.

The abort occurred in the ds24xxx_probe() because the struct w1_device
pointer was NULL. This is because that structure  is allocated by
the parent device uclass (by .per_child_platdata_auto_alloc_size)
and thus the correct accessor is dev_get_parent_platdata() not
dev_get_platdata()

Commit 768f23dc ("ARM: socfpga: Put stack at the end of SRAM") broke
those socfpga boards that keep the bootcounter at the end of the
internal SRAM as the bootcounter needs 8 bytes by default and thus the
very first SPL call to board_init_f_alloc_reserve overwrites the
bootcounter.

This patch allows to move the initial stack pointer down a bit by
checking if CONFIG_SYS_BOOTCOUNT_ADDR is located in the internal SRAM
area and then using this address as location for the start of the
stack pointer.

No new macros / defines are added by this approach.

Workaround and bug fix for Freescale PowerPC

Add workaround for Freescale USB erratum A005275.
Correct RCW macros for T1080.

Per T1040RM (Rev. 1, 08/2015), there are 2 issues with the RCW EC2
settings.

- The value of FSL_CORENET_RCWSR13_EC2_FM1_GPIO is wrong and should
  be 0x04000000 (value of 1 in RCW bit [420:421])
- Value of 2/3 are reserved in RCW bit [420:421], hence there is no

At the moment we rely on the infamous get_ram_size() function to learn
the actual DRAM size in U-Boot proper. This function has two issues:
1) It only works if the DRAM size is a power of two. We start to see
boards which have 3GB of (usable) DRAM, so this does not fit anymore.
2) As U-Boot has no notion of reserved memory so far, it will happily
ride through the DRAM, possibly stepping on secure-only memory. This
could be a region of DRAM reserved for OP-TEE or some other secure
payload, for instance. It will most likely crash in that case.

As the SPL DRAM init routine has very accurate knowledge of the actual
DRAM size, lets propagate this wisdom to U-Boot proper.
We re-purpose a currently reserved word in our SPL header for that.
The SPL itself stores the detected DRAM size there, and bumps the SPL
header version number in that case. U-Boot proper checks for a valid
SPL header and a high enough version number, then uses the DRAM size
from there. If the SPL header field is not sufficient, we fall back to
the old DRAM scanning routine.

Part of the DRAM might be present and probed by SPL, but not accessible
by the CPU. They're restricted in the main U-Boot binary, when accessing
the DRAM size from SPL header.

For A80 it should be a much higher value (8GiB), but as I have no A80
device to test and originally U-Boot only supports 2GiB DRAM on A80, it
currently still falls under the 2GiB situation.

On Allwinner SoCs we use some free bytes at the beginning of the SPL image
to store various information. We have a version byte to allow updates,
but changing this always requires all tools to be updated as well.

Introduce the concept of semantic versioning [1] to the SPL header:
The major part of the version number only changes on incompatible
updates, a minor number bump indicates backward compatibility.
This patch just documents the major/minor split, adds some comments
to the header file and uses the versioning information for the existing
users.
