* [POWERPC] Fix rheap alignment problemLi Yang2006-10-02

* [POWERPC] Add powerpc get/set_rtc_time interface to new generic rtc classKim Phillips2006-10-02
| | | | | | | | | | | | | Add powerpc get/set_rtc_time interface to new generic rtc class. This abstracts rtc chip specific code from the platform code for rtc-over-i2c platforms. Specific RTC chip support is now configured under Device Drivers -> Real Time Clock. Setting time of day from the RTC on startup is also configurable. this time without the potentially platform breaking initcall.

| * POWERPC: Bring the fs_no calculation to the relevant SoC enumerationVitaly Bordug2006-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The fs_no mean used to be fs_enet driver driven, hence it was an enumeration across all the possible fs_enet "users" in the SoC. Now, with QE on the pipeline, and to make DTS descriptions more clear, fs_no features relevant SoC part number, with additional field to describe the SoC type. Another reason for that is now not only fs_enet is going to utilize those stuff. There might be UART, HLDC, and even USB, so to prevent confusion and be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were updated in that concern, as well as the relevant DTS.

| * POWERPC: overhaul with cpm2_map mechanismVitaly Bordug2006-09-21
| | | | | | | | | | | | | | | | | | Incorporating the new way of cpm2 immr access, introduced in the previous patch, into CPM2 peripheral devices (fs_enet and cpm_uart). Both ppc and powerpc approved working( real actions taken in powerpc only, ppc just has a wrapper to keep init stuff consistent). Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com>
| * POWERPC: Get rid of remapping the whole immrVitaly Bordug2006-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The stuff below cleans up the code attempting to remap the whole cpm2_immr early, as well as places happily assuming that fact. This is more like the 2.4 legacy stuff, and is at least confusing and unclear now. To keep the world comfortable, a new mechanism is introduced: before accessing specific immr register/register set, one needs to map it, using cpm2_map(<reg>), for instance, access to CPM command register will look like volatile cpm_cpm2_t *cp = cpm2_map(im_cpm); keeping the code clear, yet without "already defined somewhere" cpm2_immr. So far, unmapping code is not implemented, but it's not a big deal to add it, if the whole idea makes sense. Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com>
| * POWERPC: Add support for the mpc8560 eval boardVitaly Bordug2006-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the 8560 evaluation board fully supported under arch/powerpc, as the first board with CPM2 SoC peripherals. The brand new devicetree nodes are introduced (intending to be a subset of the QuiccEngine-equipped models, with dts sources placed into the kernel according to the new convention. Assuming all the preceding stuff applied (PAL+fs_enet related+ CPM_UART update), the both TSEC eth ,FCC Eths, and both SCC UARTs are working. The relevant drivers are still capable to drive users in ppc, which was verified with 8272ADS (SCC uart+FCC eth). This is also verified on mpc8540 and actually make it work (PCI stuff working as well) Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com>

Unfortunately at least one device seems to like doing this - the Gigabyte iRAM. This is only done for the master right now (which is fine for the iRAM as it is SATA), as with PATA some combinations of ATAPI device seem to fool the check into seeing a drive that isn't there if it is applied to the slave.

Only separate irq for the non-uniform secondary port was implemented while all other fields (host flags, transfer mode...) of the secondary port simply shared those of the first. For ata_piix combined mode, which ATM is the only user of non-uniform ports, this causes the secondary port assume the wrong type. This can cause PATA port to use SATA ops, which results in bogus check on PCS and detection failure. This patch adds ata_probe_ent->pinfo2 which points to optional port_info for the secondary port. For the time being, this seems to be the simplest solution. This workaround will be removed together with ata_probe_ent itself after init model is updated to allow more flexibility.

The dummy port is used as placeholder for stolen legacy port. This allows libata to guarantee that index_of(ap) == ap->port_no == actual_device_port_no, and thus to remove error-prone ap->hard_port_no. As it's used only when one port of a legacy controller is reserved by some other entity (e.g. IDE), the focus is on keeping the added *code* complexity at minimum, so dummy port allocates all libata core resources and acts as a normal port. It just has all dummy port_ops. This patch only implements dummy port. The following patch will make libata use it for stolen legacy ports. Signed-off-by: Tejun Heo <htejun@gmail.com>

Longer term Jeff also wants to move the request_irq/free_irq out of core which will make this even cleaner. tj: folded in three followup patches - ata_piix-fix, broken-arch-fix and fix-new-legacy-handling, and separated per-dev xfermask into separate patch preceding this one. Folded in fixes are... * ata_piix-fix: fix build failure due to host_set->next removal * broken-arch-fix: add missing include/asm-*/libata-portmap.h * fix-new-legacy-handling: * In ata_pci_init_legacy_port(), probe_num was incorrectly incremented during initialization of the secondary port and probe_ent->n_ports was incorrectly fixed to 1. * Both legacy ports ended up having the same hard_port_no. * When printing port information, both legacy ports printed the first irq.

It introduces some new APIs which allow libata to be used without allocating a virtual scsi host. New APIs: ata_sas_port_alloc - Allocate an ata_port ata_sas_port_init - Initialize an ata_port (probe device, etc) ata_sas_port_destroy - Free an ata_port allocated by ata_sas_port_alloc ata_sas_slave_configure - configure scsi device ata_sas_queuecmd - queue a scsi command, similar to ata_scsi_queuecomand These new APIs can be used either directly by a SAS LLDD or could be used by the SAS transport class. Possible usage for a SAS LLDD would be: scsi_scan_host target_alloc ata_sas_port_alloc slave_alloc ata_sas_port_init slave_configure ata_sas_slave_configure Commands received by the LLDD for SATA devices would call ata_sas_queuecmd. Device teardown would occur with: slave_destroy port_disable target_destroy ata_sas_port_destroy Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
