Merge branch 'master' of git://git.denx.de/u-boot-arm

Albert's rework of the linker scripts conflicted with Simon's making
everyone use __bss_end.  We also had a minor conflict over
README.scrapyard being added to in mainline and enhanced in
u-boot-arm/master with proper formatting.

**** Behind the scene ******
The structure created is named with a special prefix (__u_boot_list_cmd_)
and placed by the linker in a special section.
The structure created is named with a special prefix and placed by
the linker in a special section using the linker lists mechanism
(see include/linker_lists.h)
This makes it possible for the final link to extract all commands
compiled into any object code and construct a static array so the
command can be found in an array starting at _u_boot_list_cmd__start.
command array can be iterated over using the linker lists macros.
To ensure that the linker does not discard these symbols when linking
full U-Boot we generate a list of all the commands we have built (based
on the sections mentioned above) and use that to force the linker to
first enter the symbol as undefined in the output object so that there
is then a need for the symbol to be kept (this is the UNDEF_SYM logic in
the Makefile).
The linker lists feature ensures that the linker does not discard
these symbols when linking full U-Boot even though they are not
referenced in the source code as such.
If a new board is defined do not forget to define the command section
by writing in u-boot.lds ($(TOPDIR)/board/boardname/u-boot.lds) these
3 lines:
.u_boot_list : {
#include "u-boot.lst";
KEEP(*(SORT(.u_boot_list*)));

If you are experiencing hangups/data-aborts when trying to display a BMP image,
the following might be relevant to your situation...
Some architectures cannot handle unaligned memory accesses, and an attempt to
perform one will lead to a data abort. On such architectures it is necessary to
make sure all data is properly aligned, and in many situations simply choosing
a 32 bit aligned address is enough to ensure proper alignment. This is not
always the case when dealing with data that has an internal layout such as a
BMP image:
BMP images have a header that starts with 2 byte-size fields followed by mostly
32 bit fields. The packed struct that represents this header can be seen below:
typedef struct bmp_header {
/* Header */
char signature[2];
__u32 file_size;
__u32 reserved;
__u32 data_offset;
... etc
} __attribute__ ((packed)) bmp_header_t;
When placed in an aligned address such as 0x80a00000, char signature offsets
the __u32 fields into unaligned addresses (in our example 0x80a00002,
0x80a00006, and so on...). When these fields are accessed by U-Boot, a 32 bit
access is generated at a non-32-bit-aligned address, causing a data abort.
The proper alignment for BMP images is therefore: 32-bit-aligned-address + 2.

USING AM335x NETBOOT FEATURE
Some boards (like TI AM335x based ones) have quite big on-chip RAM and
have support for booting via network in ROM. The following describes
how to setup network booting and then optionally use this support to flash
NAND and bricked (empty) board with only a network cable.
I. Building the required images
1. You have to enable generic SPL configuration options (see
docs/README.SPL) as well as CONFIG_SPL_NET_SUPPORT,
CONFIG_ETH_SUPPORT, CONFIG_SPL_LIBGENERIC_SUPPORT and
CONFIG_SPL_LIBCOMMON_SUPPORT in your board configuration file to build
SPL with support for booting over the network. Also you have to enable
the driver for the NIC used and CONFIG_SPL_BOARD_INIT option if your
board needs some board-specific initialization (TI AM335x EVM does).
If you want SPL to use some Vendor Class Identifier (VCI) you can set
one with CONFIG_SPL_NET_VCI_STRING option. am335x_evm configuration
comes with support for network booting preconfigured.
2. Define CONFIG_BOOTCOMMAND for your board to load and run debrick
script after boot:
#define CONFIG_BOOTCOMMAND \
"setenv autoload no; " \
"bootp; " \
"if tftp 80000000 debrick.scr; then " \
"source 80000000; " \
"fi"
(Or create additional board configuration with such option).
3. Build U-Boot as usual
$ make <your_board_name>
You will need u-boot.img and spl/u-boot.bin images to perform
network boot. Copy them to u-boot-restore.img and
u-boot-spl-restore.bin respectively to distinguish this version
(with automatic restore running) from the main one.
II. Host configuration.
1. Setup DHCP server (recommended server is ISC DHCPd).
- Install DHCP server and setup it to listen on the interface you
chose to connect to the board (usually configured in
/etc/default/dhcpd or /etc/default/isc-dhcp-server). Make sure there
are no other active DHCP servers in the same network segment.
- Edit your dhcpd.conf and subnet declaration matching the address
on the interface. Specify the range of assigned addresses and bootfile
to use. IMPORTANT! Both RBL and SPL use the image filename provided
in the BOOTP reply but obviously they need different images (RBL needs
raw SPL image -- u-boot-spl-restore.bin while SPL needs main U-Boot
image -- u-boot-restore.img). So you have to configure DHCP server to
provide different image filenames to RBL and SPL (and possibly another
one to main U-Boot). This can be done by checking Vendor Class
Identifier (VCI) set by BOOTP client (RBL sets VCI to "DM814x ROM v1.0"
and you can set VCI used by SPL with CONFIG_SPL_NET_VCI_STRING option,
see above).
- If you plan to use TFTP server on another machine you have to set
server-name option to point to it.
- Here is sample configuration for ISC DHCPd, assuming the interface
used to connect to the board is eth0, and it has address 192.168.8.1:
subnet 192.168.8.0 netmask 255.255.255.0 {
range dynamic-bootp 192.168.8.100 192.168.8.199;
if substring (option vendor-class-identifier, 0, 10) = "DM814x ROM" {
filename "u-boot-spl-restore.bin";
} elsif substring (option vendor-class-identifier, 0, 17) = "AM335x U-Boot SPL" {
filename "u-boot-restore.img";
} else {
filename "uImage";
}
}
2. Setup TFTP server.
Install TFTP server and put image files to it's root directory
(likely /tftpboot or /var/lib/tftpboot or /srv/tftp). You will need
u-boot.img and spl/u-boot-spl-bin files from U-Boot build directory.
III. Reflashing (debricking) the board.
1. Write debrick script. You will need to write a script that will
be executed after network boot to perform actual rescue actions. You
can use usual U-Boot commands from this script: tftp to load additional
files, nand erase/nand write to erase/write the NAND flash.
2. Create script image from your script. From U-Boot build directory:
$ ./tools/mkimage -A arm -O U-Boot -C none -T script -d <your script> debrick.scr
This will create debrick.scr file with your script inside.
3. Copy debrick.scr to TFTP root directory. You also need to copy
there all the files your script tries to load via TFTP. Example script
loads u-boot.img and MLO. You have to create these files doing regular
(not restore_flash) build and copy them to tftpboot directory.
4. Boot the board from the network, U-Boot will load debrick script
and run it after boot.
