* PPC: Add print_bats() to lib_ppc/bat_rw.cBecky Bruce2008-06-03-0/+42
| | | | | | | | | This function prints the values of all the BAT register pairs - I needed this for debug earlier this week; adding it to lib_ppc so others can use it (and add it to reginfo commands if so desired). Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
* PPC: Change lib_ppc/bat_rw.c to use high batsBecky Bruce2008-06-03-41/+97
| | | | | | | | Currently, this code only deals with BATs 0-3, which makes it useless on systems that support BATs 4-7. Add the support for these registers. Signed-off-by: Becky Bruce <Becky.bruce@freescale.com>
* PPC: Create and use CONFIG_HIGH_BATSBecky Bruce2008-06-03-7/+84
| | | | | | | | | | | Change all code that conditionally operates on high bat registers (that is, BATs 4-7) to look at CONFIG_HIGH_BATS instead of the myriad ways this is done now. Define the option for every config for which high bats are supported (and enabled by early boot, on parts where they're not always enabled) Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | The nand_info array is declared as extern in several .c files. Those days, nand.h contains a reference to the array, so there is no need to declare it elsewhere.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AT91CAP9 revC CPU has a few differences over the previous, revB CPU which was distributed in small quantities only (revA was an internal Atmel product only). The revC silicon needs a special initialisation sequence to switch from the internal (imprecise) RC oscillator to the external 32k clock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing the AT91CAP9/AT91SAM9 port, a number of header files were copied from the Linux kernel sources. This patch explicitly specifies this origin for all the copied headers, and for those missing copyright information, adds it. Additionaly, the header file 'at91sam926x_mc.h' has been superceeded in the latest kernel sources by 'at91sam9_smc.h'. The copyright information has been confirmed by the AT91 Linux kernel maintainer, Andrew Victor <avictor.za@gmail.com>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the specified delay is very short, the cycle counter may go past the "end" time we are waiting for before we get around to reading it.

| * | | avr32: Use the same entry point for reset and exception handlingHaavard Skinnemoen2008-05-27-74/+122
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the reset vector is always aligned to a very large boundary, we can save a couple of KB worth of alignment padding by placing the exception vectors at the same address. Deciding which one it is is easy: If we're handling an exception, the CPU is in Exception mode. If we're starting up after reset, the CPU is in Supervisor mode. So this adds a very minimal overhead to the reset path (only executed once) and the exception handling path (normally never executed at all.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pm_init() was always more about clock initialization than anything else.
