      powerpc/85xx: use fdt_create_phandle() to create the Fman firmware phandles · a2c1229c
      由 Timur Tabi 提交于 
      Function fdt_create_phandle() conveniently creates new phandle properties
using both "linux,phandle" and "phandle", so it should be used by all code
that wants to create a phandle.

The Fman firmware code, which embeds an Fman firmware into the device tree,
was creating the phandle properties manually.  Instead, change it to use
fdt_create_phandle().

      fdt: update fdt_alloc_phandle to use fdt_get_phandle · 50bf17bd
      由 Timur Tabi 提交于 
      The device tree compiler, dtc, can use "phandle" and/or "linux,phandle"
properties to specify the phandle for any node.  By default, it uses
both, but "linux,phandle" is deprecated.  One day, we'd like to stop using
"linux,phandle", but U-boot needs to support both properties equally
first.

fdt_alloc_phandle() generates a unique phandle, but it was only checking
the "linux,phandle" properties.  Instead, we use fdt_get_phandle(),
which checks both properties automatically.  This ensures that we
support dtbs that only use "phandle".

The side-effect is that fdt_alloc_phandle() now takes twice as long, since
it has to check for two properties instead of one in each node that it
searches.

      fdt: check for fdt errors in fdt_create_phandle · 3c927ccc
      由 Timur Tabi 提交于 
      fdt_create_phandle() was ignoring errors from fdt_set_phandle().  If an
error occurs, print an error message and return 0, which is an invalid
phandle.  We also need to change the return type for fdt_create_phandle()
to indicate that it cannot return an error code.

      fdt: Add a do_fixup_by_path_string() function · 8ddb10ea
      由 Chunhe Lan 提交于 
      The do_fixup_by_path_string() will set the specified node's property to the
value contained in "status". It would just be an inline wrapper for
do_fixup_by_path() that calls strlen on the argument.

      NAND: davinci: choose correct 1-bit h/w ECC reg · 60161943
      由 Laurence Withers 提交于 
      In nand_davinci_readecc(), select the correct NANDF<n>ECC register based
on CONFIG_SYS_NAND_CS rather than hardcoding the choice of NANDF1ECC.
This allows 1-bit hardware ECC to work with chip select other than CS2.

Note this now matches the usage in nand_davinci_enable_hwecc(), which
already had the correct handling, and allows refactoring to a single
function encapsulating the register read.

Without this fix, writing NAND pages to a chip not wired to CS2 would
result in in the ECC calculation always returning FFFFFF for each
512-byte segment, and reading back a correctly written page (one with
ECC intact) would always fail. With this fix, the ECC is written and
verified correctly.
