The GPMC is a unified memory controller dedicated for interfacing
with external memory devices like
- Asynchronous SRAM-like memories and ASICs
- Asynchronous, synchronous, and page mode burst NOR flash
- NAND flash
- Pseudo-SRAM devices
This driver will take care of setting up the GPMC based on
the settings specified in the Device tree and then
probe its children.

The nor->addr_width tracks number of address bytes used in
read/program/erase ops and eventually set to 4 for >16MB chips, regardless
of flash's internal address mode. For Infineon SEMPER flash's, we use
Read/Write Any Register commands for configuration and status check.
These commands take 3- or 4-byte address depending on flash's internal
address mode.

Re-sync again on some linux part, add some fixes for fsl_elbc from
Pali and switch
imx8mn bsh to use nand base ident
For nand subsystem tested on:
- imx8mn Macronix MX30LF4G18AC
- P2020 based board Turris 1.1 for fsl_elbc
mbus driver is initialized from arch_cpu_init() callback which is called
before relocation. This driver stores lot of functions and structure
pointers into global variables, so it is data position dependent.
Therefore after relocations all pointers are invalid and driver does not
work anymore as all pointers referes to the old memory, which overlaps with
CONFIG_SYS_LOAD_ADDR and ${loadaddr}.
For example U-Boot fuse command crashes if loadaddr memory is cleared or
rewritten by some image loaded by U-Boot load command.
mw.w ${loadaddr} 0x0 10000
fuse read 0 1 2
Fix this issue by removing of all mbus global variables in which are stored
pointers to structures or functions which changes during relocation. And
replace it by direct function calls (not via pointers). With this change
fuse command finally works.

Signed-off-by: Tom Rini <trini@konsulko.com>
Currently, add_mtd_partitions_of() can be used only if dev field of
mtd_info struct is populated. It's the case, for example, for a spi nor
flash, which has a DT compatible "jedec,spi-nor" and an associated
device. mtd->dev is populated in spi_nor_scan().
But in case of a raw nand node, mtd_info's dev field can't be populated
as flash node has no compatible, so no associated device.
add_mtd_partitions_of() can't be used to parse "partitions" subnode.
To remove this constraint, add an ofnode field in mtd_info struct
which reference the DT flash node. This new field is populated by
nand_scan_tail(). This new field will be used by add_mtd_partitions_of()
to parse the flash node for "partitions" defined in DT.

Most of the frequencies are not rounded up to a proper number.
When we need to devide these frequencies to get a number for example
frequency in Mhz, we see it as one less than the actual intended value.
Ex: If we want to get Mhz from frequency 199999994hz, we will calculate
it using div64_u64(199999994, 1000000) and we will get 199Mhz in place
of 200Mhz.

At present if an optional Kconfig value needs to be used it must be
bracketed by #ifdef. For example, with this Kconfig setup:
config WIBBLE
bool "Support wibbles, the world needs more wibbles"
config WIBBLE_ADDR
hex "Address of the wibble"
depends on WIBBLE
then the following code must be used:
#ifdef CONFIG_WIBBLE
static void handle_wibble(void)
{
int val = CONFIG_WIBBLE_ADDR;
...
}
#endif
static void init_machine()
{
...
#ifdef CONFIG_WIBBLE
handle_wibble();
#endif
}
Add a new IF_ENABLED_INT() to help with this. So now it is possible to
write, without #ifdefs:
static void handle_wibble(void)
{
int val = IF_ENABLED_INT(CONFIG_WIBBLE, CONFIG_WIBBLE_ADDR);
...
}
static void init_machine()
{
...
if (IS_ENABLED(CONFIG_WIBBLE))
handle_wibble();
}
The value will be CONFIG_WIBBLE_ADDR if CONFIG_WIBBLE is defined and will
produce a build error if not.. This allows us to reduce the use of #ifdef
in the code, ensuring that the compiler still checks the code even if it
is not ultimately used for a particular build.
Add a CONFIG_IF_ENABLED_INT() version as well.
If an attempt is made to use a value that does not exist (i.e. when the
conditional is not enabled), an error about a non-existing function is
generated, e.g.:

All supplied callback methods in U-Boot do nothing, but the
