* MPC5121e ADS PCI support take 3John Rigby2008-03-02-6/+56
| | | | | | | | | | | | | | | | Adds PCI support for MPC5121 Tested with drivers/net/rtl8139.c Support is conditional since PCI on old silicon does not work. ads5121_PCI_config turns on PCI In this version, condition compilation of PCI code has been moved from ifdef in board/ads5121/pci.c to board/ads5121/Makefile as suggested by Jean-Christophe PLAGNIOL-VILLARD Signed-off-by: John Rigby <jrigby@freescale.com>
* Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on 32bit ↵Shinya Kuribayashi2008-02-23-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | targets. ---------------------------------------------------------------- Olaf Hering [Wed, 17 Oct 2007 06:27:13 +0000 (23:27 -0700)] Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on 32bit targets. GCC can be made to warn about usage of long long types with ISO C90 (-ansi), but only with -pedantic. You can write this in a way that even then it doesn't cause warnings, namely by: #ifdef __GNUC__ __extension__ typedef __signed__ long long __s64; __extension__ typedef unsigned long long __u64; #endif The __extension__ keyword in front of this switches off any pedantic warnings for this expression.

| * 86xx: Fix GUR PCI config registers properly.Jon Loeliger2008-02-20-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in commit 975a083a5ef785c414b35f9c5b8ae25b26b41524 where I tried to "8610HPCD: Fix typos in two PCI setup registers", I botched it due to not realizing that 8610 and 8641 had different Global Utility Register defintions, one of which was like 85xx, and the other wasn't. Correct this problem by introducing two symbols, one for each 86xx SoC, but neither of which is named anything like 85xx. My bad. Lovely Wednesday with git bisect. You know.

|/ | | | | | | | | | | | R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc will refuse to use load/store multiple insns; instead, it issues a list of simple load/store instructions upon function entry and exit, resulting in bigger code size, which in turn makes the build for a few boards fail.

* ppc4xx: Add functionality to GPIO supportLawrence R. Johnson2008-01-04-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes two additions to GPIO support: First, it adds function gpio_read_in_bit() to read the a bit from the GPIO Input Register (GPIOx_IR) in the same way that function gpio_read_out_bit() reads a bit from the GPIO Output Register (GPIOx_OR). Second, it modifies function gpio_set_chip_configuration() to provide an additional option for configuring the GPIO from the "CFG_4xx_GPIO_TABLE". According to the 440EPx User's Manual, when an alternate output is used, the three-state control is configured in one of two ways, depending on the particular output. The first option is to select the corresponding alternate three-state control in the GPIOx_TRSH/L registers. The second option is to select the GPIO Three-State Control Register (GPIOx_TCR) in the GPIOx_TRSH/L registers, and set the corresponding bit in the GPIOx_TCR register to enable the output. For example, the Manual specifies configuring the GPIO00 Alternate 1 Signal (PreAddr07) to use the alternate three-state control (first option), and specifies configuring the GPIO32 Alternate 1 Signal (USB2OM0) with the output enabled in the GPIOx_TCR register (second option). Currently, gpio_set_chip_configuration() configures all alternate signal outputs to use the first option. This patch allow the second option to be selected by setting the "out_val" element in the table entry to "GPIO_OUT_1". The first option is used when the "out_val" element is set to "GPIO_OUT_0". Because "out_val" is not currently used when an alternate signal is selected, and because all current GPIO tables set "out_val" to "GPIO_OUT_0" for all alternate signals, this patch should not change any existing configurations.

This patch adds a stub implementation which simply returns the physical address cast to a uchar * for all architectures except AVR32, which converts the physical address to an uncached virtual mapping. unmap_physmem() is a no-op on all architectures, but if any architecture needs to do such mappings through the TLB, this is the hook where those TLB entries can be invalidated.
