* nios2: consolidate reset initializationThomas Chou2010-04-24-5/+4
| | | | | | | Global interrupt should be disabled from the beginning. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Signed-off-by: Scott McNutt <smcnutt@psyent.com>
* altera_jtag_uart: bypass when no jtag connectionThomas Chou2010-04-24-2/+10
| | | | | | | | | | | This patch adds an option to bypass output waiting when there is no jtag connection. This allows the jtag uart work similar to a serial uart, ie, boot even without connection. This option is enabled with CONFIG_ALTERA_JTAG_UART_BYPASS Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Signed-off-by: Scott McNutt <smcnutt@psyent.com>

* nios2: add 64 bits swab supportThomas Chou2010-04-24-0/+6
| | | | | | | | This patch adds 64 bits swab support. Most 32 bits processors use this. We need 64 bits swab for UBI. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Signed-off-by: Scott McNutt <smcnutt@psyent.com>

| * | ppc4xx: TLB init file cleanupStefan Roese2010-04-19-676/+313
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds new macros, with frequently used combinations of the 4xx TLB access control and storage attibutes. Additionally the 4xx init.S files are updated to make use of these new macros. Resulting in easier to read TLB definitions. Additionally some init.S files are updated to use the mmu header for the TLB defines, instead of defining their own macros. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge cpu and lib cache code. Flush cache before disabling. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | | microblaze: Flush cache before jumping to kernelMichal Simek2010-04-16-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is used max cache size on system which doesn't define cache size. Signed-off-by: Michal Simek <monstr@monstr.eu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | WB cache use different instruction that WT cache but the major code is that same. That means that wdc.flush on system with WT cache do the same thing as before. You need newer toolchain with wdc.flush support. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | | microblaze: Change initialization sequenceMichal Simek2010-04-16-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | env_relocation should be called first. Added stdio_init too. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | | microblaze: Change cache report messagesMichal Simek2010-04-16-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | It is more accurate to show that caches are OFF instead of FAIL. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | | microblaze: Fix interrupt handler codeMichal Simek2010-04-16-17/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is better to read ivr and react on it than do long parsing from two regs. Interrupt controller returs actual irq number. Signed-off-by: Michal Simek <monstr@monstr.eu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | I would like to handle case where system doesn't contain intc that's why I need timer initialization out of intc code. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | | microblaze: Fix irq.S codeMichal Simek2010-04-16-120/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is ancient code. There is possible to save several instructions just if we use offset instead of addik Signed-off-by: Michal Simek <monstr@monstr.eu>

| * | fsl_i2c: Added a callpoint for i2c_board_late_initRichard Retanubun2010-04-19-3/+27
| |/ | | | | | | | | | | | | This patch adds a callpoint in i2c_init that allows board specific i2c board initialization (typically for i2c bus reset) that is called after i2c_init operations, allowing the i2c_board_late_init function to use the pre-configured i2c bus speed and slave address.
* | Move arch/ppc to arch/powerpcStefan Roese2010-04-21-877/+879
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.

* ppc4xx: Add option for PPC440SPe ports without old Rev. A supportStefan Roese2010-04-14-1/+3
| | | | | | | | | | | The 440SPe Rev. A is quite old and newer 440SPe boards don't need support for this CPU revision. Since removing support for this older version simplifies the creation for newer U-Boot ports, this patch now enables 440SPe > Rev. A support by creating the CONFIG_440SPE_REVA define. By defining this in the board config header, Rev. A will still be supported. Otherwise (default for newer board ports), Rev. A will not be supported. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: alpr: Remove some not needed commands to make image fit againStefan Roese2010-04-14-1/+3
| | | | | | | | | | The latest changes increased the size of the alpr image a bit more. Now it doesn't fit into the 256k reserved for it. This patch now removes the commands "loads" and "loadb" which are not needed in the production systems.

* Move architecture-specific includes to arch/$ARCH/include/asmPeter Tyser2010-04-13-11/+9
| | | | | | | | This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>"Peter Tyser2010-04-13-36/+36
| | | | | | | | | | The appropriate include/asm-$ARCH directory should already by symlinked to include/asm so using the whole "asm-$ARCH" path is unnecessary. This change should also allow us to move the include/asm-$ARCH directories into their appropriate lib/$ARCH/ directories. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* Rename lib_generic/ to lib/Peter Tyser2010-04-13-321/+321
| | | | | | | | Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser2010-04-13-232/+232
| | | | | | | | | Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Change directory-specific CFLAGS to use full pathPeter Tyser2010-04-13-25/+30
| | | | | | | | | | | | | | | | | | Previously, a specific file or directory could be compiled with custom CFLAGS by adding a Makefile variable such as: CFLAGS_dlmalloc.o = <custom flags for common/dlmalloc.c> or CFLAGS_lib = <custom flags for lib directory> This method breaks down once multiple files or directories share the same path. Eg FLAGS_fileA = <custom flags> would incorrectly result in both dir1/fileA.c and dir2/fileA.c being compiled with <custom flags>. This change allows finer grained control which we need once we move lib_$ARCH to arch/$ARCH/lib/ and lib_generic/ to lib/. Without this change all lib/ directories would share the same custom CFLAGS.

* Create CPUDIR variablePeter Tyser2010-04-13-32/+33
| | | | | | | | | | | | The CPUDIR variable points to the location of a target's CPU directory. Currently, it is set to cpu/$CPU. However, using $CPUDIR will allow for more flexibility in the future. It lays the groundwork for reorganizing U-Boot's directory structure to support a layout such as: arch/$ARCH/cpu/$CPU/* (architecture with multiple CPU types) arch/$ARCH/cpu/* (architecture with one CPU type) Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
