tools: mxsboot: pre-fill buffer with 0xff, not 0

2023-12-13T18:33:57+00:00

The tool works for me, with imx28 and NAND memory, but the resulting
blocks are reported as bad, both by u-boot and the kernel.

This makes it impossible to erase from Linux (for an upgrade without
console access, for example -- u-boot can "nand scrub" but linux can't).

pre-filling with 0xff creates a proper boot loader image, but no
bad-block marker is there when written to flash.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

mxsboot: remove unused include

2016-02-21T10:09:19+00:00

Commit 276d3ebb883024d753cd9c69ab2fd243ffa1262e removed htole32() but missed
to remove the corresponding header. This is annoying, since BSD systems do not
have endian.h.

tools: mxsboot: Use more portable cpu_to_le32()

2016-02-02T20:01:17+00:00

Currently when building mxsboot on certain machines it reports:

  HOSTCC  tools/mxsboot
  tools/mxsboot.c: In function 'mx28_create_sd_image':
  tools/mxsboot.c:560: warning: implicit declaration of function 'htole32'
  /tmp/cchLIV6q.o: In function 'main':
  mxsboot.c:(.text+0x6d8): undefined reference to 'htole32'
  mxsboot.c:(.text+0x6e7): undefined reference to 'htole32'
  mxsboot.c:(.text+0x6f6): undefined reference to 'htole32'
  mxsboot.c:(.text+0x705): undefined reference to 'htole32'
  mxsboot.c:(.text+0x711): undefined reference to 'htole32'
  /tmp/cchLIV6q.o:mxsboot.c:(.text+0x71d): more undefined references to
  'htole32' follow
  collect2: ld returned 1 exit status
  make[1]: *** [tools/mxsboot] Error 1
  make: *** [tools] Error 2

The solution is to use cpu_to_le32() instead which is more portable,
just like other U-Boot tools [1] do.

mxs: mxsboot: fix endianess for sd boot images

2015-09-13T08:19:40+00:00

Running mxsboot on a big-endian system produces a sd image which
cannot be started by the i.MX28 ROM. It complains on the debug
uart as following:
0x8020a009
          0x80502008
0x8020a009
          0x80502008
...

Enforcing all fields within the BCB to little-endian make
the image bootable again.

tools: mxsboot: calculate ECC block level dynamically

2015-09-02T13:26:11+00:00

For pages of 2048 bytes the current setting of the ECC Error Correction Level
is only true for an oob size of 64 bytes and wrong for all others.

Instead of hard-coding every possible combination of page size and oob size use
the dynamic calculation of the ECC strength introduced in commit
6121560d7714d6d8e41ce1687a1388a1a8fea4cb.
