Currently USB Host isn't functional on the MPC8315E boards, for two reasons as described below. MPC8315 Reference Manual says: "The USB DR unit must have the same clock ratio as the encryption core unit, unless one of them has its clock disabled." The encryption core also drives I2C clock, so it is enabled and is equal to 01. That means USBDRCM should be 01 here. Plus, according to MPC8315E-RDB schematics, USB unit consumes CLK_IN clock from the 24.00MHz oscillator, which means we must adjust REFSEL bits as well. p.s. Idially we should rework whole 83xx/usb.c code, in two steps: 1. Move SCCR code to the U-Boot; 2. Implement fsl,usb-clock property in the device tree, so usb.c could decide what clock exactly to use on per-board basis. Though, today we're not in a hurry since there is just one 8315e board out there. Signed-off-by:

As suggested by Timur Tabi, we match on the old compat node ID for one version and warn accordingly. If we don't do this, we plunge people who try to use an old DTB into silent boot death with no clear indication of what the problem is. This patch should be removed at the beginning of the 2.6.27 dev cycle. It is only meant to ease the transition in the short term. Signed-off-by:

The rheap allocation function, rh_alloc, could call kmalloc with GFP_KERNEL. This can sleep, which means you couldn't hold a spinlock while called rh_alloc. Change all kmalloc calls to use GFP_ATOMIC so that it won't sleep. This is safe because only small blocks are allocated. Signed-off-by:

This adds in the device tree source for the SBC8641D, based largely on the mpc8641_hpcn.dts. The biggest differences are the lack of a complex IRQ mapping (since no Uli/i8259 cascade) and the different layout of devices on the localbus node. Signed-off-by:

global_dbcr0 needs to be a per cpu set of save areas instead of a single global on all processors. Also, we switch to using DBCR0_IDM to determine if the user space app is being debugged as its a more consistent way. In the future we should support features like hardware breakpoint and watchpoints which will have DBCR0_IDM set but not necessarily DBCR0_IC (single step). Signed-off-by: -

Freescale UPM can be used to adjust localbus timings or to generate orbitrary, pre-programmed "patterns" on the external Localbus signals. This patch implements few routines so drivers could work with UPMs in safe and generic manner. So far there is just one user of these routines: Freescale UPM NAND driver. Signed-off-by:

Similarly to what is done for PQ1-based platforms, this patch resets the PQ2 Communication Processor Module in cpm2_reset() when early debugging is not enabled. This helps avoiding conflicts when the boot loader configured the CPM in an unexpected way. Signed-off-by:

This patch modifies the Embedded Planet EP8248E device tree to reference the SMC paramater RAM base register instead of the parameter RAM allocated by the boot loader. The cpm_uart driver will allocate parameter RAM itself, making the serial port initialisation independent of the boot loader. The patch adds the parameter RAM allocated by the boot loader in the CPM muram node, making it available to the kernel. Signed-off-by:

This patch relocates the buffer descriptors and the SMC parameter RAM at the end of the first CPM muram chunk, as described in the device tree. This allows device trees to stop excluding SMC parameter ram allocated by the boot loader from the CPM muram node. Signed-off-by:

This patch adds a new generic device tree processing function that retrieves virtual reg addresses from the device tree to the bootwrapper code. It also updates the bootwrapper code to use the new function. dt_get_virtual_reg() retrieves the virtual reg addresses from the "virtual-reg" property. If the property can't be found, it uses the "reg" property and walks the tree to translate it to absolute addresses. Signed-off-by:

This patch allocates parameter RAM for SMC serial ports without relying on previous initialisation by a boot loader or a wrapper layer. SMC parameter RAM on CPM2-based platforms can be allocated anywhere in the general-purpose areas of the dual-port RAM. The current code relies on the boot loader to allocate a section of general-purpose CPM RAM and gets the section address from the device tree. This patch modifies the device tree address usage to reference the SMC parameter RAM base pointer instead of a pre-allocated RAM section and allocates memory from the CPM dual-port RAM when initialising the SMC port. CPM1-based platforms are not affected. Signed-off-by:

The architecture allows for "Book-E" style debug interrupts to either go to critial interrupts of their own debug interrupt level. To allow for a dynamic kernel to support machines of either type we want to be able to compile in the interrupt handling code for both exception levels. Towards this goal we renamed the debug handling macros to specify the interrupt level in their name (DEBUG_CRIT_EXCEPTION/DebugCrit and DEBUG_DEBUG_EXCEPTION/DebugDebug). Additionally, on the Freescale Book-e parts we expanded the exception stacks to cover the maximum case of needing three exception stacks (normal, machine check and debug). There is some kernel text space optimization to be gained if a kernel is configured for a specific Freescale implementation but we aren't handling that now to allow for the single kernel image support.

When we moved to arch/powerpc we actively tried to avoid using the ppc_md.setup_io_mappings(). Currently no board ports use it so let's remove it to avoid any new boards using it. Also, remove early_serial_map() since we don't even have a call out for it in arch/powerpc. Signed-off-by:

There is logic in platforms/peries/lpars.c which checks if the user has specified a console on the command line, and refrains from adding a preferred console entry for the hvc/hvsi console if they have. This trips up if you use "netconsole=foo" on the command line, and has the result that you get _only_ the netconsole, because the hvc device is never added as a preferred console. Worse still if you get the netconsole configuration wrong somehow, you end up with no console at all. As it turns out we don't need to worry about checking the command line. If the user has specified "console=foo", then foo will be set as the preferred console when the command line is parsed in start_kernel(), much later than the pseries code, and so the latter setting will take effect.

This changes the way we calculate how much space to reserve for the pHyp dump. Currently we reserve 256MB only. With this change, the code first checks to see if an amount has been specified on the boot command line with the "phyp_dump_reserve_size" option, and if so, uses that much. Otherwise it computes 5% of total ram and rounds it down to a multiple of 256MB, and uses the larger of that or 256MB. This is for large systems with a lot of memory (10GB or more). The aim is to have more space available for the kernel on reboot on machines with more resources. Although the dump will be collected pretty fast and the memory released really early on allowing the machine to have the full memory available, this alleviates any issues that can be caused by having way too little memory on very very large systems during those few minutes.
