+STMicroelectronics SoC DWMAC glue layer controller
+
+The device node has following properties.
+
+Required properties:
+ - compatible   : Can be "st,stih415-dwmac", "st,stih416-dwmac" or
+   "st,stid127-dwmac".
+ - reg          : Offset of the glue configuration register map in system
+   configuration regmap pointed by st,syscon property and size.
+
+ - reg-names    : Should be "sti-ethconf".
+
+ - st,syscon    : Should be phandle to system configuration node which
+   encompases this glue registers.
+
+ - st,tx-retime-src: On STi Parts for Giga bit speeds, 125Mhz clocks can be
+   wired up in from different sources. One via TXCLK pin and other via CLK_125
+   pin. This wiring is totally board dependent. However the retiming glue
+   logic should be configured accordingly. Possible values for this property
+
+           "txclk" - if 125Mhz clock is wired up via txclk line.
+           "clk_125" - if 125Mhz clock is wired up via clk_125 line.
+
+   This property is only valid for Giga bit setup( GMII, RGMII), and it is
+   un-used for non-giga bit (MII and RMII) setups. Also note that internal
+   clockgen can not generate stable 125Mhz clock.
+
+ - st,ext-phyclk: This boolean property indicates who is generating the clock
+  for tx and rx. This property is only valid for RMII case where the clock can
+  be generated from the MAC or PHY.
+
+ - clock-names: should be "sti-ethclk".
+ - clocks: Should point to ethernet clockgen which can generate phyclk.
+

-The 3Com Etherlink Plus (3c505) driver.
-
-This driver now uses DMA.  There is currently no support for PIO operation.
-The default DMA channel is 6; this is _not_ autoprobed, so you must
-make sure you configure it correctly.  If loading the driver as a
-module, you can do this with "modprobe 3c505 dma=n".  If the driver is
-linked statically into the kernel, you must either use an "ether="
-statement on the command line, or change the definition of ELP_DMA in 3c505.h.
-
-The driver will warn you if it has to fall back on the compiled in
-default DMA channel. 
-
-If no base address is given at boot time, the driver will autoprobe
-ports 0x300, 0x280 and 0x310 (in that order).  If no IRQ is given, the driver
-will try to probe for it.
-
-The driver can be used as a loadable module.
-
-Theoretically, one instance of the driver can now run multiple cards,
-in the standard way (when loading a module, say "modprobe 3c505
-io=0x300,0x340 irq=10,11 dma=6,7" or whatever).  I have not tested
-this, though.
-
-The driver may now support revision 2 hardware; the dependency on
-being able to read the host control register has been removed.  This
-is also untested, since I don't have a suitable card.
-
-Known problems:
- I still see "DMA upload timed out" messages from time to time.  These
-seem to be fairly non-fatal though.
- The card is old and slow.
-
-To do:
- Improve probe/setup code
- Test multicast and promiscuous operation
-
-Authors:
- The driver is mainly written by Craig Southeren, email
- <craigs@ineluki.apana.org.au>.

- IRQ/address detection, some changes) and this README by

+                Linux 在 AArch64 中带标记的虚拟地�
+                =================================
+
+作者: Will Deacon <will.deacon@arm.com>
+日期: 2013 年 06 月 12 日
+
+本文档简述了在 AArch64 地�转�系统中�供的带标记的虚拟地��其在
+AArch64 Linux 中的潜在用途。
+
+内核�供的地�转�表�置使通过 TTBR0 完�的虚拟地�转�（�用户空间
+映射），其虚拟地�的最高 8 �（63:56）会被转�硬件所忽略。这�机制
+让这些��供应用程�自由使用，其注�事项如下：
+
+        (1) 内核�求所有传递到 EL1 的用户空间地�带有 0x00 标记。
+            这�味�任何�带用户空间虚拟地�的系统调用（syscall）
+            �数 *必须* 在陷入内核�使它们的最高字节被清零。
+
+        (2) �零标记在传递信�时�被�存。这�味�在应用程�中利用了
+            标记的信�处�函数无法�赖 siginfo_t 的用户空间虚拟
+            地�所�带的包�其内部域信�的标记。此规则的一个例外是
+            当信�是在调试观察点的异常处�程�中产生的，此时标记的
+            信�将被�存。
+
+        (3) 当使用带标记的指针时需特别留心，因为仅对两个虚拟地�
+            的高字节，C 编译器很�能无法判断它们是��的。
+
+此构架会阻止对带标记的 PC 指针的利用，因此在异常返回时，其高字节
+将被设置�一个为 “55� 的扩展符。
