[U-Boot] [PATCH 00/14] powerpc/p4080: add support for FMan ethernet in Independent mode

[Mingkai Hu]

This patchset add support for the P4080's datapath accelation architecture
in independent mode, and do some code refactor of the file tsec.c.

1. Add the releated MAC controller support, includeing dTSEC and 10GEC
2. Add support for FMan ethernet in Independent mode
3. Add PHY support (VSC8244 and VSC8234) to a new file fsl_phy.c which
   can be reused by other code, such tsec and uec code.
4. tsec code cleanup
5. Move all the PHY code in tsec.c to fsl_phy.c to make it reuseable.

Based on the latest WD's U-Boot tree. Tested on P4080DS and MPC8536DS
board with SGMII card.

[PATCH 01/14] powerpc/p4080: Add function to report which lane is used for a prtcl
[PATCH 02/14] powerpc/fman: add PHY support for dTSEC
[PATCH 03/14] powerpc/fman: add dTSEC controller support
[PATCH 04/14] powerpc/fman: add 10GEC controller and PHY support
[PATCH 05/14] powerpc/qoirq: Add support for FMan ethernet in Independent mode
[PATCH 06/14] powerpc/corenet_ds: Add fman support
[PATCH 07/14] tsec: use IO accessories to access the register
[PATCH 08/14] tsec: arrange the code to avoid useless function declaration
[PATCH 09/14] tsec: use general ethernet MII register struct(tsec_mii_t)
[PATCH 10/14] tsec: refactor the PHY code to make it reuseable
[PATCH 11/14] PHY: add some Vitesse phy support
[PATCH 12/14] PHY: add some Broadcom phy support

[U-Boot] [PATCH 09/14] tsec: use general ethernet MII register struct(tsec_mii_t)

[Mingkai Hu]

This will pave the way to move the PHY code to fsl_phy.c which
will be reused by all other code.

Is this possible to assign the clear definition about bit fields with phy
registers
rather than hard-code hex value?
I think clear definitions will help both other vendor and your customers,
whom are the ODM/OEM vendors is easier to debug with these phy chips.

Hope you can agree with this suggestions.

I suggest we re-order these patches to first deal with tsec changes and refactor of the phy code.  After which we should introduce fman driver code that shares fsl_phy.c

These patches also break some fundamental rules about patches:
1. some patches aren't used by anything
2. some patches break functionality

OK, I'll reorder the patchset and take care of the above rules in the next version.
Thanks for your comments.

General question should we use DTSEC name to match p4080 manual for this ?

Wondering if we should use dtsec_ here since that matches P4080 Manual and possible removes some confusion with tsec enet controller.

The "& 0xffff" is unnecessary since phy_reg is a u16, so it can never be larger
than 0xffff.

CamelCase variables?

Should any of these be 2011?

Libraries are now .o files, not .a files.  Take a look at the other Makefiles to
see how they've recently changed.

What exactly happens here?  If you run out of memory, you return a pointer
anyway?  Shouldn't you return NULL here or something?

Just FYI, this code will only work on systems that have NOR flash mapped to I/O
space.  If the customer boots from NAND and doesn't have any NOR flash on his
board, then CONFIG_SYS_FMAN_FW_ADDR will be invalid.  In addition, I don't see
any code that passes the value of CONFIG_SYS_FMAN_FW_ADDR to the kernel via
"fman_ucode".

Why do we sometimes do "asm("sync");" and sometimes we do "__asm__ __volatile__
("sync");"?  And why do we have hard-coded asm anyway?  There is a sync()
function that does this already.

If you're going to do a timeout, do it the same way everyone else does.  Start
with the timeout value, and decrement the variable.  Something like this:

	timeout = 0x10000; (why a hex number anyway?)
	while (!(txbd->status & TxBD_READY) && --timeout)
		udelay(1000);

Delete this "return ;".  It doesn't do anything.

This is silly.  SLOT1 == 1, SLOT2 == 2, etc.  Just delete this enum and use numbers.
