* powerpc/85xx: verify the device tree before booting LinuxTimur Tabi2011-07-29-0/+93
| | | | | | | | | | | | | | | Introduce ft_verify_fdt(), a function that is called after the device tree has been fixed up, that displays warning messages if there is a mismatch between the physical addresses of some devices that U-Boot has configured with what the device tree says the addresses are. This is a particular problem when booting a 36-bit device tree from a 32-bit U-Boot (or vice versa), because the physical address of CCSR is wrong in the device tree. When the operating system boots, no messages are displayed, so the user generally has no idea what's wrong.

* powerpc/85xx: Handle the lack of L2 cache on P2040/P2040EKumar Gala2011-07-29-9/+37
| | | | | | | | | | The P2040/P2040E have no L2 cache. So we utilize the SVR to determine if we are one of these devices and skip the L2 init code in cpu_init.c and release. For the device tree we skip the updating of the L2 cache properties but we still update the chain of caches so the CPC/L3 node can be properly updated.

* powerpc/85xx: Add support for P2041[e] XAUI in SERDESKumar Gala2011-07-29-5/+21
| | | | | | | | | | | | | | | We add XAUI_FM1 into the SERDES tables for P2041[e] devices. However for the P2040[e] devices that dont support XAUI we handle this at runtime via SVR checks. If we are on a P2040[e] device the SERDES functions will behave as follows: is_serdes_prtcl_valid() will always report invalid if prtcl passed in is XAUI_FM1. serdes_get_prtcl() will report NONE if the prtcl in the table is set to XAUI_FM1.

* powerpc/85xx: Adding configuration for DCSRCR to enable 32M accessStephen George2011-07-29-1/+17
| | | | | | | | | | | | | | | Configuring DCSRCR to define the DCSR space to be 1G instead of the default 4M. DCSRCR only allows selection of either 4M or 1G. Most DCSR registers are within 4M but the Nexus trace buffer is located at offset 16M within the DCSR. Configuring the LAW to be 32M to allow access to the Nexus trace buffer.

| | | | | | | | | | | | | | | | | When booting with a ramdisk we bump the amount of memory reserved for the device tree by FDT_RAMDISK_OVERHEAD. However we did not increase the actual size in the device tree blob to match. Its possible on boundary cases that we dont have enough memory according to the device tree blob and get errors like: WARNING: could not set linux,initrd-end FDT_ERR_NOSPACE We can easily fix this by setting the device tree size at the same time we bump the amount of memory reserved for the device tree.

* powerpc/85xx: remove SERDES4 soft-reset work-aroundTimur Tabi2011-07-11-22/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some P4080 rev1 errata work-arounds, notably erratum SERDES4, required a bank soft-reset after the bank was configured and enabled, even though enabling a bank causes it to reset. Because the reset was required for multiple errata, it was not properly enclosed in an #ifdef, and so was not removed with all the other rev1 errata work-arounds. Erratum SERDES-8 says that the clocks for bank 3 needs to be enabled if bank 2 is enabled, but this was not being done for SERDES protocols 0xF and 0x10. The bank reset also happened to enable bank 3 (apparently an undocumented feature). Simply removing the reset breaks these two protocols. It turns out that every time we call enable_bank(), we do want at least one lane of the bank enabled, either because the bank is supposed to be enabled, or because we need the clock from that bank enabled. For erratum SERDES-A001, we don't want to modify srds_lpd_b[] when we call enable_bank(), because that array is used elsewhere to determine if the bank is available. Note that the side effect of these changes is that the work-arounds for these two errata are now linked. Specifically, if SERDES-A001 is enabled, then we need SERDES-8 enabled as well. Because this was the only SERDES bank soft-reset, there is no need to implement a work-around for erratum SERDES-A003. Also fix an off-by-one error in a printf().
