      zlib: handle overflow while calculating available stream input size · 92faa8b1
      由 Anatolij Gustschin 提交于 
      If compressed data is located in sectors at the end of the flash and
it's offset + input stream size > 0xFFFFFFFF, the uncompressing time
is very long, since processing of the stream is done bytewise (and
not blockwise) due to overflow in inflate_fast() while calculation
and checking for enough input available.

Check for this overflow condition and limit the available stream
input size to the actually max. possible input size. This fixes
the problem.

The issue is easily reproduceable by placing a gziped bitmap in flash,
e.g. at FFF80000, and running 'bmp' commands like 'bmp info FFF80000'
or 'bmp display FFF80000'. The uncompressing can take up to 3 sec.
whereas it should normaly take a fraction of a second. If the
'splashimage' environment variable points to this address, the
booting time also increases significantly.

      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.
