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.

Conflicts:
	arch/arm/cpu/ixp/u-boot.lds
	arch/arm/cpu/u-boot.lds

Build tested for all of ARM and run-time tested on am335x_evm.

-The structure created is named with a special prefix (__u_boot_list_cmd_)

+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";

+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.
