2014-07-23stdio: Pass device pointer to stdio methodsSimon Glass
At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>
2013-11-08netconsole loses 2nd character of inputSuriyan Ramasami
Netconsole loses the second character when used as input by either setenv stdin nc or setenv stdin serial,nc if using CONSOLE_CONSOLE_MUX Before a nc_send_packet() to echo the input, a check is done to see if nc_ether is valid. If its not, it waits for an arp request and then sends the packet (which contains the first character of line to be displayed as output). As part of reaping the arp request, the second character is consumed. We protect this by making the call to NetLoop(NETCONS) between input_recursion.

2012-09-24net: Improve the speed of netconsoleJoe Hershberger
Previously u-boot would initialize the network interface for every network operation and then shut it down again. This makes sense for most operations where the network in not known to be needed soon after the operation is complete. In the case of netconsole, it will use the network for every interaction with the shell or every printf. This means that the network is being reinitialized very often. On many devices, this intialization is very slow. This patch checks for consecutive netconsole actions and leaves the ethernet hardware initialized between them. It will still behave the same old way for all other network operations and any time another network operation happens between netconsole operations.

2012-09-24net: Make netconsole src and dest ports configurableJoe Hershberger
It is desirable to use different port numbers for sending and receiving packets with netconsole in the case where you have more than one device on the local subnet with netconsole enabled for broadcast. When they use the same port for both, any output from one will look like input to the other. This is typlically not desirable. This patch allows the input and output ports to be specified separately in the environment.

Add several levels of DEBUG prints so that you can limit the noise to the severety of your problem.

2009-07-18stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD
So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.
