* net: uec_phy: actually increment the timeout counterKim Phillips2008-03-07-1/+2
| | | | | | | | allow u-boot to recover (and, e.g., switch to another interface) in the case where a PHY does not report autonegotiation is complete within its two second timeout value. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
* fix QE firmware uploading limitTimur Tabi2008-03-03-1/+1
| | | | | | | Fix a typo in qe_upload_firmware() that prevented uploading firmware on systems with more than one RISC core. Signed-off-by: Timur Tabi <timur@freescale.com>
* net: uec_phy: handle 88e1111 rev.B2 erratum 5.6Kim Phillips2008-03-02-0/+8
| | | | | | | | | | erratum 5.6 states the autoneg completion bit is functional only if the autoneg bit is asserted. This fixes any secondarily-issued networking commands on non-gigabit links on the mpc8360 mds board. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
* QE: Move FDT support into a common fileKumar Gala2008-02-12-1/+93
| | | | | | | Move the flat device tree setup for QE related devices into a common file shared between 83xx & 85xx platforms that have QE's. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Remove annoying debug printout for PHY less boards.Joakim Tjernlund2008-01-16-2/+1

* net: reduce boot latency on QE UEC based boardsKim Phillips2008-01-16-48/+79
| | | | | | | | | | | | | | | actually polling for PHY autonegotiation to finish enables us to remove the 5 second boot prompt latency present on QE based boards. call to qe_set_mii_clk_src in init_phy, and mv call to init_phy from uec_initialize to uec_init by Joakim Tjernlund; autonegotiation wait code shamelessly stolen from tsec driver. also rm unused CONFIG_RMII_MODE code.

* QE UEC: Extend number of supported UECs to 4David Saada2008-01-15-1/+42
| | | | | | | | | This patch extends the number of supported UECs to 4. Note that the problem of QE thread resources exhaustion is resolved by setting the correct number of QE threads according to Ethernet type (GBE or FE).

* Fix Ethernet init() return codesBen Warren2008-01-10-3/+3
| | | | | | | | | | | | | | | | | | Change return values of init() functions in all Ethernet drivers to conform to the following: >=0: Success <0: Failure All drivers going forward should return 0 on success. Current drivers that return 1 on success were left as-is to minimize changes.

* 85xx: add ability to upload QE firmwareTimur Tabi2008-01-09-0/+275
| | | | | | | | | | | 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. Add command-line command "qe fw" to take a firmware blob in memory and upload it. Update ft_cpu_setup() on 85xx to create the 'firmware' device tree node if U-Boot has uploaded a firmware. Fully define 'struct rsp' in immap_qe.h to include the actual RISC Special Registers.

* Fix numerous bugs in the 8568 UEC supportAndy Fleming2007-08-16-3/+3
| | | | | | | | | | | | | | | | | | | | | Actually, fixed a large bug in the UEC for *all* platforms. How did this ever work? uec_init() did not follow the spec for eth_init(), and returned 0 on success. Switch it to return the link like tsec_init() (and 0 on error) The immap for the 8568 was defined based on MPC8568, rather than CONFIG_MPC8568 CONFIG_QE was off CONFIG_ETHPRIME was set to "Freescale GETH". Now is "FSL UEC0" Fixed a comment about the ranges for CONFIG_ETHPRIME if TSEC_ENET is enabled Signed-off-by: Andy Fleming <afleming@freescale.com>

* mpc83xx: Fix alternating tx error / tx buffer not ready bug in QE UECEmilian Medve2007-03-02-1/+1
| | | | | | | | The problem is not gcc4 but the code itself. The BD_STATUS() macro can't be used for busy-waiting since it strips the 'volatile' property from the bd variable. gcc3 was working by pure luck. This is a follow on patch to "Fix the UEC driver bug of QE"
