of: clean up OF_CONTROL ifdef conditionals

2015-08-18T17:46:05+00:00

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROL

2015-08-18T17:46:04+00:00

As we discussed a couple of times, negative CONFIG options make our
life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ...
and here is another one.

Now, there are three boards enabling OF_CONTROL on SPL:
 - socfpga_arria5_defconfig
 - socfpga_cyclone5_defconfig
 - socfpga_socrates_defconfig

This commit adds CONFIG_SPL_OF_CONTROL for them and deletes
CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert
the logic.

spl: spl_mmc: Add option to boot from a MMC partition with offset

2015-07-24T07:46:45+00:00

This patch introduces the option to boot from a MMC card parition with
an offset. This can be done by using both defines together:

define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION 1
define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR    ((160 << 10) / 512)

The example above loads the main U-Boot at offset 160KiB from the MMC
partition 1.

spl: Add a debug string before the jump to U-Boot

2015-07-21T23:39:29+00:00

As a debug option, add positive confirmation that SPL has completed
execution. This can help with diagnosing the location of unexpected hangs.

dm: spl: Allow device tree/driver model in board_init_f()

2015-07-21T23:39:28+00:00

Add an spl_init() function that does basic init such that board_init_f() can
use simple malloc(), device tree and driver model. Each one is set up only
if enabled for SPL.

Note: We really should refactor SPL such that there is a single
board_init_f() and rename the existing weak board_init_f() functions
provided by boards, calling them from the single board_init_f().

spl: spl_mmc: MMC boot mode provisions checks

2015-06-18T20:11:42+00:00

This allows using only one of either raw or fs mode for SPL mmc boot, without
the need to have provisions for the other. In particular, a device may have
U-Boot installed on a file system on the mmc, without ever needing to read
U-Boot from raw memory. Thus, there is no reason to provide a sector or
partition for raw mode. This allows this behaviour and still provides a robust
fallback mechanism in case provisions for both modes are defined.
