Function ioremap_nocache seems to be defined only for MIPS and Microblaze
architectures. Therefore, the function call in the emaclite driver causes
this driver to be unusable with other architectures, for example RISC-V.
Use ioremap function instead of ioremap_nocache, and include linux/io.h
instead of asm/io.h, so that ioremap function is automatically created,
if not defined by the architecture. We can switch to the ioremap function,
as Microblaze's ioremap_nocache is just empty and in MIPS implementations
of ioremap_nocache and ioremap are the same.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
Note this involves changing some dead code - the imx_lpi2c.c file.

When IP is configured with pong buffers, IP is receiving packets to ping
and then to pong buffer and than ping again.
The original logic in the driver remains there that when ping buffer is
free, pong buffer is checked too and return if both are free.
Signed-off-by: Michal Simek <michal.simek@xilinx.com>
The original logic in the driver was exchanging buffers which are used for
sending packet and tx_ping and tx_pong buffers were exchanged all the
time to ensure that IP has enough time to send the packet out.
Based on this "feature" send function was using nextbuffertouse variable
to save which buffer should be used.
Before this algorithm was called driver checked that there is free
buffer available.
This checking remains in the driver but driver tries to use tx_ping
first if available. If not, tx_pong buffer is used instead.
To reach this code the original condition is met that at least one of the
buffer should be available.
Testing doesn't show any performance drop when this patch is applied.

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing

away the ugly logic in include/fdtdec.h:
#ifdef CONFIG_OF_CONTROL
# if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
# define OF_CONTROL 0
# else
# define OF_CONTROL 1
# endif
#else
# define OF_CONTROL 0
#endif
Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.
Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.
