The BRDCFG5[SPISDHC] register field of Qixis device is used
to control SPI and SDHC signal routing.
10 = Force SDHC Mode
- SPI_CS[0] is routed to CPLD for SDHC_VS use.
- SPI_CS[1] is unused.
- SPI_CS[2:3] are routed to the TDMRiser slot.
11 = Force eMMC Mode
- SPI_CS[0:3] are routed to the eMMC card.
0X = Auto Mode
- If SDHC_CS_B=0 (SDHC card installed): Use SDHC mode
described above.
- Else SDHC_CS_B=1 (no SDHC card installed): Use eMMC
mode described above.
In default the hardware uses auto mode, but sometimes we need
to use force SDHC mode to support SD card hotplug, or SD sleep
waking up in kernel. This patch is to support force SDHC mode
by hwconfig.

This patch extends pmic_bind_children prefix matching. In addition to
the node name the property regulator-name is used while trying to match

named regulator@1 and regulator@10 for example.
I have discarded the idea of using other properties then regulator-name
as I do not see any benefit in using property compatible or even
regulator-compatible. Of course I am open to change this if there are

The DM version of do_reset has been issuing a warm-reset, which (on
some platforms keeps GPIOs and other parts of the platform active).
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
reset_cpu() or using sysreset_walk().

Update tegra to use binman for image creation. This still includes the
current Makefile logic, but a later patch will remove this. Three output
files are created, all of which combine
SPL and U-Boot:
u-boot-tegra.bin - standard image
u-boot-dtb-tegra.bin - same as u-boot-tegra.bin
u-boot-nodtb-target.bin - includes U-Boot without the appended device tree
The latter is useful for build systems where the device is appended later,
perhaps after being modified.

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.

u_boot_binman_syms_size - has a binman symbol with an invalid size

In some cases we need to read symbols from U-Boot. At present we have a
a few cases which does this via 'nm' and 'grep'.
It is better to use objdump since that tells us the size of the symbols
and also whether it is weak or not.
Add a new module which reads ELF information from files. Update existing
uses of 'nm' to use this module.
