At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.Move the compatibility features into a separate header file.

The phandlep pointer returning the phandle to the caller is optional
and if it is not set when calling fdtdec_add_reserved_memory() it is
highly likely that the caller is not interested in a phandle to the
created reserved-memory area and really just wants that area added.So just don't create a phandle in that case.

The change adding fdtdec_add_reserved_memory() already protected the added
phandle against the phandlep being NULL - making the phandlep var optional.But in the early code checking for an already existing carveout this check
was not done and thus the phandle assignment could run into trouble,
so add a check there as well, which makes the function still return
successfully if a matching region is found, even though no-one wants to
work with the phandle.Fixes: c9222a08b3f7 ("fdtdec: Implement fdtdec_add_reserved_memory()")

This function can be used to set the local MAC address for the default
Ethernet interface in its device tree node. The default interface is
identified by the "ethernet" alias.One case where this is useful is for devices that store their MAC
address in a custom location. Once extracted, board code can store the
MAC address in U-Boot's control DTB so that it will automatically be
used by the Ethernet uclass.Signed-off-by: Thierry Reding

Building U-Boot with CONFIG_PCI and CONFIG_DM_PCI enabled, but
CONFIG_SPL_PCI_SUPPORT disabled, results in following linker
error:lib/built-in.o: In function `fdtdec_get_pci_bar32':
lib/fdtdec.c:305: undefined reference to `dm_pci_read_bar32'
fdtdec.c:305:(.text.fdtdec_get_pci_bar32+0x24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dm_pci_read_bar32'This is because reference to dm_pci_read_bar32() remains in lib/fdtdec.c
while SPL build does not descend into drivers/pci directory in
drivers/Makefile if CONFIG_SPL_PCI_SUPPORT is not enabled.Fix this by applying appropriate #define guards in lib/fdtdec.c.
It looks like ns16550.c has the same problem, so fixed that too.To simplify this, CONFIG_SPL_PCI_SUPPORT is renamed to CONFIG_SPL_PCI
(enables use of CONFIG_IS_ENABLED() macro).Suggested-by: Vignesh R

In some cases it may be useful to be able to change the fdt we have been
using and use another one instead. For example, the TI platforms uses an
EEPROM to store board information and, based on the type of board,
different dtbs are used by the SPL. When DM_I2C is used, a first dtb must
be used before the I2C is initialized and only then the final dtb can be
selected.
To speed up the process and reduce memory usage, introduce a new function
fdtdec_setup_best_match() that re-use the DTBs loaded in memory by
fdtdec_setup() to select the best match.Signed-off-by: Jean-Jacques Hiblot

the virtual address space of the operating system. All address used on the
command line live in this address space. So also the environment variable
${fdtcontroladdr} has to be in this address space.Commands like bootefi and booti receive the fdt address as parameter.
Without the patch ${fdtcontroladdr} cannot be used as parameter value on

When U-Boot proper is compiled with CONFIG_MULTI_DTB_FIT and tries
to call uncompress_blob(), it fails with -ENOTSUPP. This is because
the full implementation of this function which includes compression
is available only in SPL. In U-Boot proper or if the compression is
not enabled, the blob is not compressed and thus can be passed to
locate_dtb_in_fit() in fdtdec_setup() without any changes. Pass the
blob without any changes if compression is not enabled instead of
failing.Signed-off-by: Marek Vasut

In int-ll64.h, we always use the following typedefs:
typedef unsigned int u32;
typedef unsigned long uintptr_t;
typedef unsigned long long u64;This does not need to match to the compiler's .
Do not include it.The use of PRI* makes the code super-ugly. You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.Signed-off-by: Masahiro Yamada

The get_next_memory_node() always sets mem to -1 , which is incorrect,
because then every iteration of memory bank parsing will start from the
first memory bank instead of the previous one.On systems with 1 memory bank defined in DT and CONFIG_NR_DRAM_BANKS=4 ,
like ie. r8a77965-salvator-x , this will result in U-Boot incorrectly
reporting four identical memory banks with the same memory configuration.Fix this by setting mem to startoffset value, which restores the behavior
before the fixed patch was applied.Signed-off-by: Marek Vasut
