The following series based on the previous patches switch the am33xx based boards
(Phytec phyCORE and Beaglebone(black)) over to devicetree and multi image support.

I've tested this on both boards in both MLO and regular builds. They start, the
devices come up and things seem to work, but more testing would be welcomed.
Wait, I just realized that the network on Beaglebone black stopped working, I'll
have a look.

  To: barebox

The multi image startup process used to have three binaries involved:
- The lowlevel board code to initialize SDRAM
- the uncompressor
- the regular (compressed) barebox binary
Drop the uncompressor and put the uncompress code into the lowlevel
board code binary. This makes the startup process easier.

An entry function should begin with a exception header. For this to work
properly the entry function should not contain any code which gcc might
put before the header. To make this sure change the ENTRY_FUNCTION macro
so that it generates one function which only contains the exception header
and a second function which contains the original body of the entry function.

This switches the am335x Phytec phyCORE to devicetree probe support.
For now we use a linked in dtb.

As with devicetree support the binary will get too large for the
SRAM drop the configuration. It was mainly meant for debugging purposes
anyway.

From: Sascha Hauer @ 2013-11-26 16:46 UTC (permalink / raw)
  To: barebox

Storing the boot information in the image itself and passing a pointer
around between images is cumbersome and doesn't fit well with multiimage
support where the pointer we pass around is already occupied by the
devicetree.
Do the same as U-Boot does and store the boot information at the bottom
of the SRAM public stack.
To maintain the compatibility between new xloaders and older barebox
binaries we still pass the boot information to the next stage via pointer.

The Beaglebone and the AM335x Phytec phyCORE can be compiled
together, so merge the configs into a am335x_mlo_defconfig.

Why is this zero now? Are these things defined in the dts file?

It's a relocatable binary which gets relocated during runtime. The
address doesn't matter anymore, but setting it to zero helps translating
the addresses from the objdump to the running binary.

It generates smaller binaries. Does this cause trouble?

No I didn't see any problems. I used it only for MLO/xload builds by
now.

Hello Sascha,

I need some help about the booting from NAND flash. I have created the
MLO file with the pcm051_mlo_defconfig but I cant boot from NAND. I dont
know if i need more configuration.

This is the content of pcm051_mlo_defconfig:

CONFIG_ARCH_OMAP=y
CONFIG_ARCH_AM33XX=y
CONFIG_OMAP_BUILD_IFT=y
CONFIG_MACH_PCM051=y
CONFIG_OMAP_UART1=y
CONFIG_THUMB2_BAREBOX=y
# CONFIG_CMD_ARM_CPUINFO is not set
# CONFIG_MEMINFO is not set
CONFIG_ENVIRONMENT_VARIABLES=y
CONFIG_MMU=y
CONFIG_TEXT_BASE=0x402F0400
CONFIG_STACK_SIZE=0x1600
CONFIG_MALLOC_SIZE=0x1000000
CONFIG_PROMPT="MLO>"
CONFIG_SHELL_NONE=y
# CONFIG_ERRNO_MESSAGES is not set
# CONFIG_TIMESTAMP is not set
CONFIG_CONSOLE_SIMPLE=y
# CONFIG_DEFAULT_ENVIRONMENT is not set
CONFIG_DRIVER_SERIAL_NS16550=y
CONFIG_DRIVER_SERIAL_NS16550_OMAP_EXTENSIONS=y
CONFIG_DRIVER_SPI_OMAP3=y
CONFIG_MTD=y
CONFIG_MTD_M25P80=y
CONFIG_NAND=y
CONFIG_NAND_OMAP_GPMC=y
CONFIG_MCI=y
CONFIG_MCI_STARTUP=y
CONFIG_MCI_OMAP_HSMMC=y
# CONFIG_FS_RAMFS is not set
# CONFIG_FS_DEVFS is not set
CONFIG_FS_FAT=y
CONFIG_FS_FAT_LFN=y

Do you have any idea??


Thank you in advance.
Best Regards.
Carlos
