[U-Boot] [RFC] Tigon III (bcm57xx) Driver on fsl platforms

Hello all,
(Note, I am not subscribed to the list, so please make sure to keep me in Cc)
I am working on a p4080 based system (Freescale 32-bit Power). In order to support specific peripherals, I needed to have the tg3 driver. The old bcm570x driver that was removed from U-Boot some time ago does not support the 5720 chip that I'm working with (not to mention, the code is horrid), so I took the larger step of porting the FreeBSD if_bge driver to U-Boot.
This has been largely successful. The PCIe chip is detected and probed. I can RX packets without any issues, however TX has some odd issues where even though the SBD consumer ACKs the packet as coalesced (which shows that it was DMAd to the Write-FIFO), the packet never shows up on the wire. This is generally an ARP-Request packet. For the most part, once ARP succeeds, things like TFTP request and ACK packets are sent without issues. All of these packets are, for the most part, less than 60 bytes (which means the tg3 chip pads them out to 60).
Using wireshark confirms that packets are not being sent, and reading the HCOutOctets stat register after coalescing a packet confirms that it did indeed write this packet.
Another issue I'm having is that I'm currently having to pace the CSR_READ_4()/CSR_WRITE_4() macros (readl/writel) with a udelay to take care of a random hang during register read/write.
All of these issues are reproducible on a p4080ds and t4240qds. I'm not sure if either of them are specific to the platform (perhaps issues with memory mapping and DMA?), but I would appreciate some help on these problems.
Driver code attached:

+ * Broadcom BCM57xx(x)/BCM590x NetXtreme and NetLink family Ethernet driver
+ *
+ * The Broadcom BCM5700 is based on technology originally developed by
+ * Alteon Networks as part of the Tigon I and Tigon II Gigabit Ethernet
+ * MAC chips. The BCM5700, sometimes referred to as the Tigon III, has
+ * two on-board MIPS R4000 CPUs and can have as much as 16MB of external
+ * SSRAM. The BCM5700 supports TCP, UDP and IP checksum offload, jumbo
+ * frames, highly configurable RX filtering, and 16 RX and TX queues
+ * (which, along with RX filter rules, can be used for QOS applications).
+ * Other features, such as TCP segmentation, may be available as part
+ * of value-added firmware updates. Unlike the Tigon I and Tigon II,
+ * firmware images can be stored in hardware and need not be compiled
+ * into the driver.
+ *
+ * The BCM5700 supports the PCI v2.2 and PCI-X v1.0 standards, and will
+ * function in a 32-bit/64-bit 33/66Mhz bus, or a 64-bit/133Mhz bus.
+ *
+ * The BCM5701 is a single-chip solution incorporating both the BCM5700
+ * MAC and a BCM5401 10/100/1000 PHY. Unlike the BCM5700, the BCM5701
+ * does not support external SSRAM.
+ *
+ * Broadcom also produces a variation of the BCM5700 under the "Altima"
+ * brand name, which is functionally similar but lacks PCI-X support.
+ *
+ * Without external SSRAM, you can only have at most 4 TX rings,
+ * and the use of the mini RX ring is disabled. This seems to imply
+ * that these features are simply not available on the BCM5701. As a
+ * result, this driver does not implement any support for the mini RX
+ * ring.

+ * BCM570x memory map. The internal memory layout varies somewhat
+ * depending on whether or not we have external SSRAM attached.
+ * The BCM5700 can have up to 16MB of external memory. The BCM5701
+ * is apparently not designed to use external SSRAM. The mappings
+ * up to the first 4 send rings are the same for both internal and
+ * external memory configurations. Note that mini RX ring space is
+ * only available with external SSRAM configurations, which means
+ * the mini RX ring is not supported on the BCM5701.
+ *
+ * The NIC's memory can be accessed by the host in one of 3 ways:
+ *
+ * 1) Indirect register access. The MEMWIN_BASEADDR and MEMWIN_DATA
+ * registers in PCI config space can be used to read any 32-bit
+ * address within the NIC's memory.
+ *
+ * 2) Memory window access. The MEMWIN_BASEADDR register in PCI config
+ * space can be used in conjunction with the memory window in the
+ * device register space at offset 0x8000 to read any 32K chunk
+ * of NIC memory.
+ *
+ * 3) Flat mode. If the 'flat mode' bit in the PCI state register is
+ * set, the device I/O mapping consumes 32MB of host address space,
+ * allowing all of the registers and internal NIC memory to be
+ * accessed directly. NIC memory addresses are offset by 0x01000000.
+ * Flat mode consumes so much host address space that it is not
+ * recommended.
