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.

This bug is brought by the commit 3d8553f0a3 (pci: layerscape: add
LS2088A series SoC pcie support), which only updated cfg_res.start
and did not update the .end field. This causes fdt_resource_size()

This function returns the pointer to the value of a node property.
The current name ofnode_read_prop() is confusing. Follow the naming
of_get_property() from Linux.
The return type (const u32 *) is wrong. DT property values can be
strings as well as integers. This is why of_get_property/fdt_getprop
returns an opaque pointer.

The of_n_addr_cells() and of_n_size_cells() functions are useful for
getting the size of addresses in a node, but in a few places U-Boot needs
to obtain the actual property value for a node without walking up the
stack. Add functions for this and just the existing code to use it.
Add a comment to the existing ofnode functions which do not do the right
thing with a flat tree.
This fixes a problem reading PCI addresses.

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.

There is no dedicated reset signal wired up for the MX6QDL thus if the
bootloader enables the link we need some special handling to get the core
back into a state where it is safe to touch it for configuration.
While there has been some special handling in the Linux kernel to do this,
it was removed in 4.11 thus we need to do it properly in the bootloader
and therefore without this if you enable PCI in the bootloader you will hang
while booting the 4.11 kernel.
This puts the PCIe controller back into a safe state for the kernel driver
before launching the kernel.

This patch allows probing all PCIe nodes defined in DTS
even if there no device connected to such node (no link).
Without this fix the driver returns -ENODEV when the PCIe
link is down. As result the pci_init function stops
scanning bus on first empty PCIe slot and all devices
located in higher numbered buses are not discovered.

For ease of use and accounting a condition that on SH4
pci_phys_to_bus() and pci_bus_to_phys() are one in one mappings due to
unimplemented __iomem() conversion, this change fixes access to SDRAM

This change also generalizes PCI system memory configuration, which is

The change actually maps PCI I/O window to the same address on PCI bus
as it is stated by a comment, before the change transfers to the PCI I/O
space are failed due to misconfiguration of the most significant 14 bits
of the PCI address in PCIIOBR (note that it is set to 0x0).
Most probably the problem remained unnoticed, because communcation
to all tested PCI devices is done over PCI memory space only.
