When calling efi_dp_find_obj(), we usually want to find the *exact* match
of an object for a given device path. However, I ran into a nasty corner case
where I had the following objects with paths available:
Handle 0x9feffa70
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/EndEntire
Handle 0x9feffb58
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/HD(1,800,32000,2de808cb00000000,1,1)/EndEntire
and was searching for
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/HD(1,800,32000,2de808cb00000000,1,1)/EndEntire
But because our device path search looked for any substring match, it would
return
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/EndEntire
because that path is a full substring of the path we were searching for.
So this patch adapts the device path search logic to always look for exact
matches first. The way we distinguish between those cases is by looking at
whether our caller actually deals with remainders.
As a side effect, the code as is from all I can tell now never does a
substring match anymore, because it always gets called with rem=NULL, so
we always only do exact matches now.

Commit bbf75dd934 ("efi_loader: output load options in helloworld")
introduced a const variable in efi_main() called loaded_image_guid which
got populated from a constant struct.
While you would usually expect a compiler to realize that this variable
should really just be a global pointer to .rodata, gcc disagrees and instead
puts it on the stack. Unfortunately in some implementations of gcc it does
so my calling memcpy() which we do not implement in our hello world
environment.
So let's explicitly move it to a global variable which in turn puts it in
.rodata reliably and gets rid of the memcpy().

The at24 driver allows to register I2C EEPROM chips using different vendor
and devices, but the I2C subsystem does not take the vendor into account
when matching using the I2C table since it only has device entries.
But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.
So add this generic fallback to the device node compatible string to make
the device to match the driver using the OF device ID table.

This patch is enabling support for SPL QSPI boot.
First of all it is necessary to generate atf-spi.ub which is different
format than atf-uboot.ub (this can be made as legacy image too)
ADDR=`arm-xilinx-linux-gnueabi-readelf -a bl31.elf | grep "Entry point

aarch64-linux-gnu-objcopy -O binary bl31.elf bl31.bin

./tools/mkimage -A arm64 -T firmware -C none -O u-boot -a $ADDR -e $ADDR
-n "atf-for-qspi" -E -d bl31.bin atf-spi.ub
This patch is using this QSPI layout with offsets:
0 boot.bin
512k atf-ub
640k u-boot.bin
1280k u-boot.img
Which corresponding by writing these images(read from MMC)

load mmc 0 10000000 boot.bin
sf erase 0 +$filesize
sf write 10000000 0 $filesize
load mmc 0 10000000 atf-spi.ub
sf erase 0x80000 +$filesize
sf write 10000000 0x80000 $filesize
load mmc 0 10000000 u-boot.bin

load mmc 0 10000000 u-boot.img
sf erase 0x140000 +$filesize
sf write 10000000 0x140000 $filesize
For testing u-boot running in EL3 you can break atf-spi.ub like this:

sf erase 0x80000 +4
Then u-boot.img is executed.

This may cause unintended behaviour, as calling do_reset usually
indicates a desire to reset the board/platform and not just the CPU.
This changes do_reset to always request a COLD reset.
Note that programmatic uses can still invoke a WARM reset through

u-boot-dtb-tegra.bin - same as u-boot-tegra.bin

Binman construct images consisting of multiple binary files. These files
sometimes need to know (at run timme) where their peers are located. For
example, SPL may want to know where U-Boot is located in the image, so
that it can jump to U-Boot correctly on boot.
In general the positions where the binaries end up after binman has
finished packing them cannot be known at compile time. One reason for
this is that binman does not know the size of the binaries until
everything is compiled, linked and converted to binaries with objcopy.
To make this work, we add a feature to binman which checks each binary
for symbol names starting with '_binman'. These are then decoded to figure
out which entry and property they refer to. Then binman writes the value
of this symbol into the appropriate binary. With this, the symbol will
have the correct value at run time.
Macros are used to make this easier to use. As an example, this declares
a symbol that will access the 'u-boot-spl' entry to find the 'pos' value
(i.e. the position of SPL in the image):
binman_sym_declare(unsigned long, u_boot_spl, pos);
This converts to a symbol called '_binman_u_boot_spl_prop_pos' in any
binary that includes it. Binman then updates the value in that binary,
ensuring that it can be accessed at runtime with:
ulong u_boot_pos = binman_sym(ulong, u_boot_spl, pos);
This assigns the variable u_boot_pos to the position of SPL in the image.
