Onboard AMD Flash chip does not support buffered writes Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06sc520: Allow boards to override udelayGraeme Russ
If the board has a high precision mico-second timer, it maked sense to use it instead of the on-chip one Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Fix support for booting bzImageGraeme Russ
Add support for newer (up to 2.6.33) kernels Add zboot command which takes the address of a bzImage as its first argument and (optionally) the size of the bzImage as the second argument (the second argument is needed for older kernels which do not include the bzImage size in the header) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Provide weak PC/AT compatibility setup functionGraeme Russ
It is possibly to setup x86 boards to use non-PC/AT configurations. For example, the sc520 is an x86 CPU with PC/AT and non-PC/AT peripherals. This function allows the board to set itself up for maximum PC/AT compatibility just before booting the Linux kernel (the Linux kernel 'just works' if everything is PC/AT compliant) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Use CONFIG_SERIAL_MULTIGraeme Russ
Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06SERIAL: Enable port-mapped accessGraeme Russ
The x86 architecture exclusively uses Port-Mapped I/O (inb/outb) to access the 16550 UARTs. This patch mimics how Linux selects between Memory-Mapped and Port-Mapped I/O. This allows x86 boards to use CONFIG_SERIAL_MUTLI and drop the custom serial port driver Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Fix copying of Real-Mode code into RAMGraeme Russ
Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Pass relocation offset into Global DataGraeme Russ
In order to locate the 16-bit BIOS code, we need to know the reloaction offset. Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Move GDT to a safe location in RAMGraeme Russ
Currently, the GDT is either located in FLASH or in the non-relocated U-Boot image in RAM. Both of these locations are unsafe as those locations can be erased during a U-Boot update. Move the GDT into the highest available memory location and relocate U-Boot to just below it Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Add RAM bootstrap functionalityGraeme Russ
Add a parameter to the 32-bit entry to indicate if entry is from Real Mode or not. If entry is from Real Mode, execute the destructive 'sizer' routine to determine memory size as we are booting cold and running in Flash. If not entering from Real Mode, we are executing a U-Boot image from RAM and therefore the memory size is already known (and running 'sizer' will destroy the running image) There are now two 32-bit entry points. The first is the 'in RAM' entry point which exists at the start of the U-Boot binary image. As such, you can load u-boot.bin in RAM and jump directly to the load address without needing to calculate any offsets. The second entry point is used by the real-to-protected mode switch This patch also changes TEXT_BASE to 0x6000000 (in RAM). You can load the resulting image at 0x6000000 and simple go 0x6000000 from the u-boot prompt Hopefully a later patch will completely elliminate any dependency on TEXT_BASE like a relocatable linux kernel (perfect world) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Split sc520 memory sizing versus reportingGraeme Russ
This patch allows the low-level assembler boot-strap to obtain the RAM size without calling the destructive 'sizer' routine. This allows boot-strapping from a U-Boot image loaded in RAM Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Fix sc520 memory size reportingGraeme Russ
There is an error in how the assembler version of the sc520 memory size reporting code works. As a result, it will only ever report at most the size of one bank of RAM Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Fix do_go_exec()Graeme Russ
This was broken a long time ago by a49864593e083a5d0779fb9ca98e5a0f2053183d which munged the NIOS and x86 do_go_exec() Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Add register dump to crash handlersGraeme Russ
Shamelessly steal the Linux x86 crash handling code and shove it into U-Boot (cool - it fits). Be sure to include suitable attribution to Linus Signed-off-by: Graeme Russ <graeme.russ@gmail.com>

2010-05-05cmd_onenand.c: moved to standard subcommand handlingFrans Meulenbroeks
On the fly also fixed the following things: - write help talked about a parameter oob, but that one was not used, so removed it from the help message. - the test command also allowed a force subcommand but didn't use it. eliminated the code. - do_onenand made static - do_onenand contained int blocksize; ... mtd = &onenand_mtd; this = mtd->priv; blocksize = (1 << this->erase_shift); As blocksize was not used the last two statements were unneeded so removed them. The first statement (mtd = ....) assigns to a global. Not sure if it is needed, and since I could not test this, left the line for now Signed-off-by: Frans Meulenbroeks <fransmeulenbroeks@gmail.com>
2010-05-05ppc: unused memory region too close to current stack pointerNorbert van Bolhuis
This avoids a possible overwrite of the (end of) ramdisk by u-boot. The unused memory region for ppc boot currently starts 1k below the do_bootm->bootm_start->arch_lmb_reserve stack ptr. This isn't enough since do_bootm->do_bootm_linux->boot_relocate_fdt calls printf which may very well use more than 1k stack space. Signed-off-by: Norbert van Bolhuis <nvbolhuis@aimvalley.nl>
2010-05-05allow print_size to print large numbers on 32-bit systemsTimur Tabi
Modify print_size() so that it can accept numbers larger than 4GB on 32-bit systems. Add support for display terabyte, petabyte, and exabyte sizes. Change the output to use International Electrotechnical Commission binary prefix standard. Signed-off-by: Timur Tabi <timur@freescale.com>
2010-05-05fix print_size printing fractional gigabyte numbers on 32-bit platformsTimur Tabi
In print_size(), the math that calculates the fractional remainder of a number used the same integer size as a physical address. However, the "10 *" factor of the algorithm means that a large number (e.g. 1.5GB) can overflow the integer if we're running on a 32-bit system. Therefore, we need to disassociate this function from the size of a physical address. Signed-off-by: Timur Tabi <timur@freescale.com>

2010-05-03smc911x driver frame alignment patchValentin Yakovenkov
SMSC911x chips have alignment function to allow frame payload data (which comes after 14-bytes ethernet header) to be aligned at some boundary when reading it from fifo (usually - 4 bytes boundary). This is done by inserting fake zeros bytes BEFORE actual frame data when reading from SMSC's fifo. This function controlled by RX_CFG register. There are bits that represents amount of fake bytes to be inserted. Linux uses alignment of 4 bytes. Ethernet frame header is 14 bytes long, so we need to add 2 fake bytes to get payload data aligned at 4-bytes boundary. Linux driver does this by adding IP_ALIGNMENT constant (defined at skb.h) when calculating fifo data length. All network subsystem of Linux uses this constant too when calculating different offsets. But u-boot does not use any packet data alignment, so we don't need to add anything when calculating fifo data length. Moreover, driver zeros the RX_CFG register just one line up, so chip does not insert any fake data at the beginig. So calculated data length is always bigger by 1 word. It seems that at almost every packet read we get an underflow condition at fifo and possible corruption of data. Especially at continuous transfers, such as tftp. Just after removing this magic addition, I've got tftp transfer speed as it aught to be at 100Mbps. It was really slow before. It seems that fifo underflow occurs only when using byte packing on 32-bit blackfin bus (may be because of very small delay between reads).

2010-05-03tsec: Wait for both RX and TX to stopAndy Fleming
When gracefully stopping the controller, the driver was continuing if *either* RX or TX had stopped. We need to wait for both, or the controller could get into an invalid state. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
2010-05-03net: dm9000x: use standard I/O accessorsMike Frysinger
The current dm9000x driver accesses its memory mapped registers directly instead of using the standard I/O accessors. This can cause problems on Blackfin systems as the accesses can get out of order. So convert the direct volatile dereferences to use the normal in/out macros. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
