On J7200 SoC OSPI0 and HypeFlash are muxed at HW level and only one of
them can be used at any time. J7200 EVM has both HyperFlash and OSPI
flash on board. There is a user switch (SW3.1) that can be toggled to
select OSPI flash vs HyperFlash.
Read the state of this switch via wkup_gpio0_6 line and fixup the DT
nodes to select OSPI0 vs HyperFlash

The DT nodes on J721E SoCs currently use a node name "interconnect" for
the various interconnects. This name is not following the DT schema, and
should simply be "bus". Update the fdt fixup logic to use both the current
and the expected corrected path names so that this logic won't be broken
with newer kernels.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:
<smpl>
@@
typedef bd_t;
@@
-bd_t
+struct bd_info

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.
Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

Initialize both ESM and ESM_PMIC support if available for the board.
If support is not available for either, a warning is printed out.
ESM signals are only properly routed on PM2 version of the J721E SOM,

The TI J721E EVM system on module (SOM), the common processor board, and
the associated daughtercards have on-board I2C-based EEPROMs containing
board config data. Use the board detection infrastructure to do the
following:
1) Parse the J721E SOM EEPROM and populate items like board name, board
HW and SW revision as well as board serial number into the TI common
EEPROM data structure residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing associated I2C
addresses used for on-board EEPROMs containing daughter card-specific
data. If such a card is found, parse the EEPROM data such as for
additional Ethernet MAC addresses and populate those into U-Boot
accordingly
3) Dynamically apply daughter card DTB overlays to the U-Boot (proper)
DTB during SPL execution
4) Dynamically create an U-Boot ENV variable called name_overlays
during U-Boot execution containing a list of daugherboard-specific
DTB overlays based on daughercards found to be used during Kernel
boot.
This patch adds support for the J721E system on module boards containing
the actual SoC ("J721EX-PM2-SOM", accessed via CONFIG_EEPROM_CHIP_ADDRESS),
the common processor board ("J7X-BASE-CPB"), the Quad-Port Ethernet
Expansion Board ("J7X-VSC8514-ETH"), the infotainment board
("J7X-INFOTAN-EXP") as well as for the gateway/Ethernet switch/industrial
expansion board ("J7X-GESI-EXP").
