[POWERPC] QE: Make qe_get_firmware_info reentrant

2008-03-10T18:07:27Z

The function was returning NULL the second time it was called if the firmware was uploaded from the boot loader or the first time it was called if the firmware was uploaded from the kernel. Signed-off-by: Ionut Nicu Acked-By: Timur Tabi Signed-off-by: Kumar Gala

[POWERPC] QE: Fix QE firmware uploading limit

2008-03-07T14:55:02Z

Fix a typo in qe_upload_firmware() that prevented uploading firmware on systems with more than one RISC core. Signed-off-by: Timur Tabi Signed-off-by: Kumar Gala

[POWERPC] qe_lib: fix few fluffy negligences

2008-02-06T05:57:31Z

One is intoduced by me (of_node_put() absence) and another was present already (not checking for NULL). Found by Stephen Rothwell. Signed-off-by: Anton Vorontsov Acked-by: Stephen Rothwell Signed-off-by: Kumar Gala

[POWERPC] QE: get rid of most device_types and model

2008-01-28T14:32:55Z

Now we're searching for "fsl,qe", "fsl,qe-muram", "fsl,qe-muram-data" and "fsl,qe-ic". Unfortunately it's still impossible to remove device_type = "qe" from the existing device trees because older u-boots are looking for it. Signed-off-by: Anton Vorontsov Signed-off-by: Kumar Gala

[POWERPC] QE: Add ability to upload QE firmware

2008-01-24T01:34:06Z

Define the layout of a binary blob that contains a QE firmware and instructions on how to upload it. Add function qe_upload_firmware() to parse the blob and perform the actual upload. Fully define 'struct rsp' in immap_qe.h to include the actual RISC Special Registers. Added description of a new QE firmware node to booting-without-of.txt.

[POWERPC] qe: add function qe_clock_source()

2007-12-14T04:59:27Z

Add function qe_clock_source() which takes a string containing the name of a QE clock source (as is typically found in device trees) and returns the matching enum qe_clock value. Update booting-without-of.txt to indicate that the UCC properties rx-clock and tx-clock are deprecated and replaced with rx-clock-name and tx-clock-name, which use strings instead of numbers to indicate QE clock sources.

[POWERPC] QE: change qe_setbrg() to take an enum qe_clock instead of an integer

2007-12-11T19:57:18Z

qe_setbrg() currently takes an integer to indicate the BRG number. Change that to take an enum qe_clock instead, since this enum is intended to represent clock sources. Signed-off-by: Timur Tabi Signed-off-by: Kumar Gala

[POWERPC] qe: miscellaneous code improvements and fixes to the QE library

2007-10-08T13:38:15Z

This patch makes numerous miscellaneous code improvements to the QE library. 1. Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type() (every caller of ucc_init_guemr() also calls ucc_set_type()). Modify all callers of ucc_set_type() accordingly. 2. Remove the unused enum ucc_pram_initial_offset. 3. Refactor qe_setbrg(), also implement work-around for errata QE_General4. 4. Several printk() calls were missing the terminating \n. 5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where appropriate. 6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed with the wrong value. 7. Add the protocol type to struct us_info and updated ucc_slow_init() to use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED. 8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx() 9. Add several macros in qe.h (mostly for slow UCC support, but also to standardize some naming convention) and remove several unused macros. 10. Update ucc_geth.c to use the new macros. 11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol to use when initializing the UCC in ucc_slow_init(). 12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since these are the real names of the registers. 13. Use the setbits, clrbits, and clrsetbits where appropriate. 14. Refactor ucc_set_qe_mux_rxtx(). 15. Remove all instances of 'volatile'. 16. Simplify get_cmxucr_reg(); 17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[]. 18. Updated struct ucc_geth because struct ucc_fast is not padded any more. Signed-off-by: Timur Tabi Signed-off-by: Kumar Gala

[POWERPC] Change rheap functions to use ulongs instead of pointers

2007-05-10T04:01:43Z

The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().
