Vipin Kumar [Thu, 13 Dec 2012 10:55:53 +0000 (16:25 +0530)]
usbh/ehci: Increase timeout for enumeration

The current logic reads the port status just once after usb_hub_power_on and
expects the portstatus and portchange to report the connection status
immediately and correctly.

Few pen drives are not able to report both of them immediately ie. those pens
report the connection change but not the connected state after the first read.
This opportunity once lost is gone for ever because the u-boot, unlike linux or
any other OS, works in polling mode.

This patch modifies the logic to read the port status continuously until the
portstatus and portchange both report a connection change as well as a connected
state or no connection change and no connection. This logic is placed in a
timeout of 10 sec. At the end of it, the pen drive would have either reported a
ONE or a ZERO in bit 1 of portstatus as well as portchange.

It enhances the set of pen drives which can eventually be detected by u-boot

Note: This 10 second timeout is based purely on several experiments done with
the broken pen drives

fs:ext4:write: Initialize cache aligned filename buffer

The filename buffer is allocated dynamically. It must be cache aligned.
Moreover, it is necessary to erase its content before we use it for
file name operations.

This prevents from corruption of written file names.

fs:ext4:write: Add lldiv and do_div to perform 64-32 bits division

The ext4write code has been using direct calls to 64-32 division
(/ and %).

Officially supported u-boot toolchains (eldk-5.[12].x) generate calls
to __aeabi_uldivmod(), which is niether defined in the toolchain libs
nor u-boot source tree.

Due to that, when the ext4write command has been executed, "undefined
instruction" execption was generated (since the __aeabi_uldivmod()
is not provided).

To fix this error, lldiv() for division and do_div() for modulo have
been used.

Those two functions are recommended for performing 64-32 bit number
division in u-boot.
