ARM: zynq: add separate configuration for ZC702 and ZC706

Prior to this commit, ZC702 and ZC706 shared the same configuration
and were built as follows:

ZC702: make zynq_zc70x_defconfig && make
ZC706: make zynq_zc70x_defconfig && make DEVICE_TREE=zynq-zc706

This commit introduces separate configuration for them, which makes
the next commit much easier.

Going forward, the recommended build commands are:

ZC702: make zynq_zc702_defconfig && make
ZC706: make zynq_zc706_defconfig && make

Although the old work flow is still supported, CONFIG_TARGET_ZC70X
has been marked as deprecated.  If used, the warning message is
shown to prompt users to switch to the new scheme.

9 years agoconsole: Fix pre-console flushing via cfb_console being very slow
Hans de Goede [Tue, 5 May 2015 11:13:36 +0000 (13:13 +0200)]
console: Fix pre-console flushing via cfb_console being very slow

On my A10 OlinuxIno Lime I noticed a huge (5+ seconds) delay coming from
console_init_r. This turns out to be caused by the preconsole buffer flushing
to the cfb_console. The Lime only has a 16 bit memory bus and that is already
heavy used to scan out the 1920x1080 framebuffer.

The problem is that print_pre_console_buffer() was printing the buffer once
character at a time and the cfb_console code then ends up doing a cache-flush
for touched display lines for each character.

This commit fixes this by first building a 0 terminated buffer and then
printing it in one puts() call, avoiding unnecessary cache flushes.

This changes the time for the flush from 5+ seconds to not noticable.

The downside of this approach is that the pre-console buffer needs to fit
on the stack, this is not that much to ask since we are talking about plain
text here. This commit also adjusts the sunxi CONFIG_PRE_CON_BUF_SZ to
actually fit on the stack. Sunxi currently is the only user of the pre-console
code so no other boards need to be adjusted.

9 years agomx6cuboxi: Fix Ethernet PHY detection problem
Fabio Estevam [Mon, 4 May 2015 14:22:55 +0000 (11:22 -0300)]
mx6cuboxi: Fix Ethernet PHY detection problem

mx6cuboxi sometimes fails to recognize the Ethernet PHY:

Net:   Phy 0 not found

The explanation for this behavior comes from from Rabeeh Khoury:

"The LED_ACT pin on the carrier-one boards had a pull down that
forces the phy address to 0x0; where on CuBox-i and the production
HummingBoard that pin is connected directly to LED that depending
on the pull down strength of the LED it might be sampled as '0' or '1' thus
the phy address might appear as either address 0x0 or 0x4."

"This is AR8035 implementation; in reset stage the LED pin is configured as
input, and pull up/down does matter. In this case it configures the PHY
address.

After reset is deasserted the same LED pin becomes output and then
according to the previous pull/up it should be active high/low"

One way to properly fix this behavior is to place external pull-up/down
resistors in the LED line, but from a software standpoint we can fix it
by telling phy_find_by_mask() to scan the PHY at addresses
0x0 and 0x4.
