The xics code currently has a direct and lpar variant of xics_host_map, the only difference being which irq_chip they use. If we remember which irq_chip we're using we can combine these two routines. That also allows us to have a single irq_host_ops instead of two. Signed-off-by:

pseries_mpic_init_IRQ() implements the same logic as the xics code did to find the i8259 cascade irq. Now that we've pulled that logic out into pseries_setup_i8259_cascade() we can use it in the mpic code. Signed-off-by:

Remove the xics references from xics_setup_8259_cascade(), and merge the good bits from the almost identical logic in pseries_mpic_init_IRQ(). Signed-off-by:

Michael Ellerman authored
The code in xics.c to setup the i8259 cascaded irq handler is not really xics specific, so move it into setup.c - we will clean this up further in a subsequent patch. Signed-off-by:

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:

1. Detect (and bail out on) more conditions that violate the assumptions of the setup code -- we assume in such cases that the device tree is correct and reflects what the firmware did. 2. The inbound memory mask calculation was wrong. 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:
