powerpc/boot: Use correct zlib types for comparison

2014-08-13T05:13:45Z

Avoids this warning: arch/powerpc/boot/gunzip_util.c:118:9: warning: comparison of distinct pointer types lacks a cast Signed-off-by: Benjamin Herrenschmidt

[POWERPC] boot: Simplify gunzip_finish

2007-10-03T01:48:43Z

Call gunzip_partial to calculate the remaining length and copy the data to the user buffer. This makes it shorter and reduces duplication. Signed-off-by: Milton Miller Acked-by: David Gibson Signed-off-by: Paul Mackerras

[POWERPC] boot: Record header bytes in gunzip_start

2007-10-03T01:48:43Z

Record the number of header bytes skipped in the total bytes read field. This is needed for the initramfs parsing code to find the end of the zip file. Signed-off-by: Milton Miller Acked-by: David Gibson Signed-off-by: Paul Mackerras

[POWERPC] boot: More verbose gunzip error message

2007-04-27T11:13:49Z

Change the error message in gunzip_exactly to be more verbose. Besides the identifier being unrelated to the current function name, the user had no indication if the corruption was near the beginning or the end. Signed-off-by: Milton Miller Acked-by: David Gibson Signed-off-by: Paul Mackerras

[POWERPC] bootwrapper: Add a fatal error helper

2007-03-26T05:11:20Z

Add a macro fatal that calls printf then exit. User must include stdio.h. Typically replaces 3 lines with 1, although I added back some whitespace. Signed-off-by: Milton Miller Signed-off-by: Paul Mackerras

[POWERPC] Add documentation for the zImage's gunzip convenience functions

2007-03-16T05:38:19Z

This patch adds documenting comments to the gunzip convenience functions added in commit ad9d2716cfc1cda5a7e0d7bc0db45e3af8a4adbb. It also removes a stray newline, and an unused global variable. Signed-off-by: David Gibson Signed-off-by: Paul Mackerras

[POWERPC] zImage: Add more flexible gunzip convenience functions

2007-03-13T02:35:01Z

At present, arch/powerpc/boot/main.c includes a gunzip() function which is a convenient wrapper around zlib. However, it doesn't conveniently allow decompressing part of an image to one location, then the remainder to a different address. This patch adds a new set of more flexible convenience wrappers around zlib, moving them to their own file, gunzip_util.c, in the process. These wrappers allow decompressing sections of the compressed image to different locations. In addition, they transparently handle uncompressed data, avoiding special case code to handle uncompressed vmlinux images. The patch also converts main.c to use the new wrappers, using the new flexibility to avoid decompressing the vmlinux's ELF header twice as we did previously. That in turn means we avoid extending our allocations for the vmlinux to allow space for the extra copy of the ELF header. Signed-off-by: David Gibson Signed-off-by: Paul Mackerras
