mpc8272_ads.c is using BCSR bits definitions from pq2ads.h, but according to User's Guide the bits are wrong for MPC8272ADS boards (I guess definitions from pq2ads should only be used for PQ2FADS boards). So, let's introduce our own definitions for MPC8272ADS, and don't include pq2ads.h. Signed-off-by:

This patch simply adds sdhci node to the device tree. We specify clock-frequency manually, so that eSDHC will work without upgrading U-Boot. Though, that'll only work for default setup (1500 MHz) on new board revisions. For non-default setups, it's recommended to upgrade U-Boot, since it will fixup clock-frequency automatically.

The earlier mpc8560 CPUs don't have the RSTCR at 0xe00b0 in the GUTS. The generic reboot code uses this tag to determine if it should be using the RSTCR for reboot, so remove it from the board definition. Signed-off-by:

Some CPU, like the MPC8560 don't have a RSTCR in the Global Utilities Block. These boards will implement their own reboot call, and not use this code, so we should only warn about the absence of the GUTS RSTCR when the default reboot code is used. Signed-off-by:

The existing fsl_rstcr_restart function is not applicable to the mpc8560. The Global Utilities Block on this earlier CPU doesn't have the control/reset register at 0xe00b0. This implements a board specific reset function that uses the RCR(Reset Control Register) of the sbc8560's EPLD to do a reset. Signed-off-by:

With flash partition entries in the DTS file, MTD might as well be enabled in the defconfig. In a similar vein, enable USB and enough related options (SCSI/ext2/ext3) so that a user can read and write to a generic USB flash drive as well. Also, this board only has the two default SOC UARTs, so adjust the UART config accordingly. Signed-off-by:

Allows interrupts to occur on the sbc834x. Currently PCI devices get assigned an incorrect IRQ and so the interrupt count never increases. This was tested with the 82546GB based dual port E1000 PCI-X NIC which uses two distinct IRQ lines on the one card. root@localhost:/root> cat /proc/interrupts | grep eth 17: 78 IPIC Level eth1 48: 27121 IPIC Level eth0 Signed-off-by:

There is 8MB flash, 8kB EEPROM and 128MB SDRAM on the sbc834x local bus, so add a localbus node in DTS with MTD partitions. The recent U-boot commit fe613cdd4eb moves u-boot to the beginning of flash, hence the legacy label on the partition at the end of flash. Signed-off-by:

Since only one of the SoC USB devices is brought out to a physical connector on the board, remove the 2nd (USB-DR) node from the DTS. Having it present and USB enabled will cause a hang at boot. Signed-off-by:

Currently _edata does not include several data sections, this causes the kernel's report of memory usage at boot to not match reality, and also prevents kmemleak from working - because it scan between _sdata and _edata for pointers to allocated memory. This mirrors a similar change made recently to the x86 linker script. Signed-off-by:

Using the radeon KMS test functionality, I verified that the AGP bridge of the Intrepid2 chipset in my PowerBook supports aperture sizes up to 256M. So allow aperture sizes up to 256M on pre-U3 bridges as well, and bump the default size to 256M. It's possible that older revisions only support smaller sizes, but it'll be easy to verify that with the raden KMS test functionality. Also, there's only a problem on an actual attempt to access the aperture beyond the maximum size supported by the hardware, and non-KMS X still defaults to using only 32M. Also use ARRAY_SIZE for the aperture size arrays. Signed-off-by:

Actually, the support is already there, but it requires newer U-Boots (to fill-in clock-frequency, and setup pin multiplexing). Though, it appears that on RDB boards USBB pins aren't multiplexed between USB and eSDHC (unlike MDS boards, where USB and eSDHC share pctl and pwrfault pins). So, for RDB boards we can safely setup pinmux and manually fill-in clock-frequency, thus making eSDHC work even with older u-boots. Signed-off-by:
