xtensa: add support for the xtensa processor architecture [1/2]

2016-08-15T22:46:38+00:00

The Xtensa processor architecture is a configurable, extensible,
and synthesizable 32-bit RISC processor core provided by Cadence.

This is the first part of the basic architecture port with changes to
common files. The 'arch/xtensa' directory, and boards and additional
drivers will be in separate commits.

image: fix IH_ARCH_... values for uImage compatibility

2016-07-21T14:47:03+00:00

Commit 555f45d8f916 ("image: Convert the IH_... values to enums")
accidentally changed some IH_ARCH_... values.

Prior to that commit, there existed a gap between IH_ARCH_M68K and
IH_ARCH_MICROBLAZE, like follows.

  #define IH_ARCH_SPARC64         11      /* Sparc 64 Bit */
  #define IH_ARCH_M68K            12      /* M68K         */
  #define IH_ARCH_MICROBLAZE      14      /* MicroBlaze   */
  #define IH_ARCH_NIOS2           15      /* Nios-II      */

The enum conversion broke the compatibility with existing uImage
files.  Reverting 555f45d8f916 will cause build error unfortunately,
so here is a more easy fix.

I dug the git history and figured out the gap was introduced by
commit 1117cbf2adac ("nios: remove nios-32 arch").  So, I revived
IH_ARCH_NIOS just for filling the gap.

I added comments to each enum block.  Once we assign a value to
IH_... it is not allowed to change it.

image: Add functions to obtain category information

2016-07-14T22:22:30+00:00

Add generic functions which can look up information about a category:

- the number of items in the category
- the category description
- an item long time
- an item short time

image: Create a table of information for each category

2016-07-14T22:22:29+00:00

Add a table that contains the category name, the number of items in each
category and a pointer to the table of items. This will allow us to use
generic code to deal with the categories.

image: Convert the IH_... values to enums

2016-07-14T22:22:28+00:00

We need to know the number of values of each category (architecture,
compression, OS and image type). To make this value easier to maintain,
convert all values to enums. The count is then automatic.

spl: fit: add support for post-processing of images

2016-07-14T22:22:21+00:00

The next stage boot loader image and the selected FDT can be post-
processed by board/platform/device-specific code, which can include
modifying the size and altering the starting source address before
copying these binary blobs to their final destination. This might be
desired to do things like strip headers or footers attached to the
images before they were packaged into the FIT, or to perform operations
such as decryption or authentication. Introduce new configuration
option CONFIG_SPL_FIT_IMAGE_POST_PROCESS to allow controlling this
feature. If enabled, a platform-specific post-process function must
be provided.

Revert "image.h: Tighten up content using handy CONFIG_IS_ENABLED() macro."

2016-05-31T14:20:14+00:00

This reverts commit 56adbb38727320375b2f695bd04600d766d8a1b3.

Since commit 56adbb387273 ("image.h: Tighten up content using handy
CONFIG_IS_ENABLED() macro."), I found my boards fail to boot Linux
because the commit changed the logic of macros it touched.  Now,
IMAGE_ENABLE_RAMDISK_HIGH and IMAGE_BOOT_GET_CMDLINE are 0 for all
the boards.

As you can see in include/linux/kconfig.h, CONFIG_IS_ENABLE() (and
IS_ENABLED() as well) can only take a macro that is either defined
as 1 or undefined.  This is met for boolean options defined in
Kconfig.  On the other hand, CONFIG_SYS_BOOT_RAMDISK_HIGH and
CONFIG_SYS_BOOT_GET_CMDLINE are defined without any value in
arch/*/include/asm/config.h .  This kind of clean-up is welcome,
but the options should be moved to Kconfig beforehand.

Moreover, CONFIG_IS_ENABLED(SPL_CRC32_SUPPORT) looks weird.
It should be either CONFIG_IS_ENABLED(CRC32_SUPPORT) or
IS_ENABLED(CONFIG_SPL_CRC32_SUPPORT).  But, I see no define for
CONFIG_SPL_CRC32_SUPPORT anywhere.  Likewise for the other three.

The logic of IMAGE_OF_BOARD_SETUP and IMAGE_OF_SYSTEM_SETUP were
also changed for SPL.  This can be a problem for boards defining
CONFIG_SPL_OF_LIBFDT.  I guess it should have been changed to
IS_ENABLED(CONFIG_OF_BOARD_SETUP).

In the first place, if we replace the references in C code,
the macros IMAGE_* will go away.

  if (IS_ENABLED(CONFIG_OF_BOARD_SETUP) {
          ...
  }
