fdt: add new fdt address parsing functions

2015-09-15T13:57:13+00:00

fdtdec_get_addr_size() hard-codes the number of cells used to represent
an address or size in DT. This is incorrect in many cases depending on
the DT binding for a particular node or property (e.g. it is incorrect
for the "reg" property). In most cases, DT parsing code must use the
properties #address-cells and #size-cells to parse addres properties.

This change splits up the implementation of fdtdec_get_addr_size() so
that the core logic can be used for both hard-coded and non-hard-coded
cases. Various wrapper functions are implemented that support cases
where hard-coded cell counts should or should not be used, and where
the client does and doesn't know the parent node ID that contains the
properties #address-cells and #size-cells.

dev_get_addr() is updated to use the new functions.

Core functionality in fdtdec_get_addr_size_fixed() is widely tested via
fdtdec_get_addr_size(). I tested fdtdec_get_addr_size_auto_noparent() and
dev_get_addr() by manually modifying the Tegra I2C driver to invoke them.

Much of the core implementation of fdtdec_get_addr_size_fixed(),
fdtdec_get_addr_size_auto_parent(), and
fdtdec_get_addr_size_auto_noparent() comes from Thierry Reding's
previous commit "fdt: Fix fdtdec_get_addr_size() for 64-bit".

mmc: dw_mmc: Probe the MMC from OF

2015-09-04T09:54:20+00:00

Rework the driver to probe the MMC controller from Device Tree
and make it mandatory. There is no longer support for probing
from the ancient qts-generated header files.

This patch now also removes previous temporary workaround.

of: clean up OF_CONTROL ifdef conditionals

2015-08-18T17:46:05+00:00

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROL

2015-08-18T17:46:04+00:00

As we discussed a couple of times, negative CONFIG options make our
life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ...
and here is another one.

Now, there are three boards enabling OF_CONTROL on SPL:
 - socfpga_arria5_defconfig
 - socfpga_cyclone5_defconfig
 - socfpga_socrates_defconfig

This commit adds CONFIG_SPL_OF_CONTROL for them and deletes
CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert
the logic.

x86: baytrail: Configure FSP UPD from device tree

2015-08-14T09:24:21+00:00

Allow for configuration of FSP UPD from the device tree which will
override any settings which the FSP was built with itself.

Modify the MinnowMax and BayleyBay boards to transfer sensible UPD
settings from the Intel FSPv4 Gold release to the respective dts files,
with the condition that the memory-down parameters for MinnowMax are
also used.

arm: socfpga: misc: Reset ethernet from OF

Reset the GMAC ethernets based on the "resets" OF node instead of ad-hoc
hardcoded values in the U-Boot code. Since we don't have a proper reset
framework in place yet, we have to do this slightly ad-hoc parsing of the
OF tree instead.

lib/fdtdec: Fix fdt_addr_t and fdt_size_t typedef

2015-08-06T13:31:36+00:00

fdt_addr_t is a physical address. It can be either 64-bit or 32-bit,
depending on the architecture. It should be phys_addr_t instead of
u64 or u32. Similarly, fdt_size_t is changed to phys_size_t.
