From 2e192b245ed36a63bab0ef576999a95e23f60ecd Mon Sep 17 00:00:00 2001
From: Simon Glass <sjg@chromium.org>
Date: Sun, 17 Jan 2016 20:53:52 -0700
Subject: Remove the cmd_ prefix from command files

Now that they are in their own directory, we can remove this prefix.
This makes it easier to find a file since the prefix does not get in the
way.

- * I2C Functions similar to the standard memory functions.
- *
- * There are several parameters in many of the commands that bear further
- * explanations:
- *
- * {i2c_chip} is the I2C chip address (the first byte sent on the bus).
- *   Each I2C chip on the bus has a unique address.  On the I2C data bus,
- *   the address is the upper seven bits and the LSB is the "read/write"
- *   bit.  Note that the {i2c_chip} address specified on the command
- *   line is not shifted up: e.g. a typical EEPROM memory chip may have
- *   an I2C address of 0x50, but the data put on the bus will be 0xA0
- *   for write and 0xA1 for read.  This "non shifted" address notation
- *   matches at least half of the data sheets :-/.
- *
- * {addr} is the address (or offset) within the chip.  Small memory
- *   chips have 8 bit addresses.  Large memory chips have 16 bit
- *   addresses.  Other memory chips have 9, 10, or 11 bit addresses.
- *   Many non-memory chips have multiple registers and {addr} is used
- *   as the register index.  Some non-memory chips have only one register
- *   and therefore don't need any {addr} parameter.
- *
- *   The default {addr} parameter is one byte (.1) which works well for
- *   memories and registers with 8 bits of address space.
- *
- *   You can specify the length of the {addr} field with the optional .0,
- *   .1, or .2 modifier (similar to the .b, .w, .l modifier).  If you are
- *   manipulating a single register device which doesn't use an address
- *   field, use "0.0" for the address and the ".0" length field will
- *   suppress the address in the I2C data stream.  This also works for
- *   successive reads using the I2C auto-incrementing memory pointer.
- *
- *   If you are manipulating a large memory with 2-byte addresses, use
- *   the .2 address modifier, e.g. 210.2 addresses location 528 (decimal).
- *
- *   Then there are the unfortunate memory chips that spill the most
- *   significant 1, 2, or 3 bits of address into the chip address byte.
- *   This effectively makes one chip (logically) look like 2, 4, or
- *   8 chips.  This is handled (awkwardly) by #defining
- *   CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW and using the .1 modifier on the
- *   {addr} field (since .1 is the default, it doesn't actually have to
- *   be specified).  Examples: given a memory chip at I2C chip address
- *   0x50, the following would happen...
- *     i2c md 50 0 10   display 16 bytes starting at 0x000
- *                      On the bus: <S> A0 00 <E> <S> A1 <rd> ... <rd>
- *     i2c md 50 100 10 display 16 bytes starting at 0x100
- *                      On the bus: <S> A2 00 <E> <S> A3 <rd> ... <rd>
- *     i2c md 50 210 10 display 16 bytes starting at 0x210
- *                      On the bus: <S> A4 10 <E> <S> A5 <rd> ... <rd>
- *   This is awfully ugly.  It would be nice if someone would think up
- *   a better way of handling this.

-	 *              address and checking for aliasing.
-	 *              This test will find single-bit
-	 *              address failures such as stuck-high,

-	 *              address and size of the region are
-	 *              selected by the caller.
-
-	 * Notes:	For best results, the selected base
-	 *              address should have enough LSB 0's to
-	 *              guarantee single address bit changes.
-	 *              For example, to test a 64-Kbyte
-	 *              region, select a base address on a
-	 *              64-Kbyte boundary. Also, select the

- * "The ExCA standard specifies that socket controllers should provide
- * two IO and five memory windows per socket, which can be independently
- * configured and positioned in the host address space and mapped to
- * arbitrary segments of card address space. " - David A Hinds. 1999
- *
- * This controller does _not_ meet the ExCA standard.
- *
- * m8xx pcmcia controller brief info:
- * + 8 windows (attrib, mem, i/o)
- * + up to two slots (SLOT_A and SLOT_B)
- * + inputpins, outputpins, event and mask registers.
- * - no offset register. sigh.
- *
- * Because of the lacking offset register we must map the whole card.
- * We assign each memory window PCMCIA_MEM_WIN_SIZE address space.
- * Make sure there is (PCMCIA_MEM_WIN_SIZE * PCMCIA_MEM_WIN_NO
- * * PCMCIA_SOCKETS_NO) bytes at PCMCIA_MEM_WIN_BASE.
- * The i/o windows are dynamically allocated at PCMCIA_IO_WIN_BASE.

+/*
+ * I2C Functions similar to the standard memory functions.
+ *
+ * There are several parameters in many of the commands that bear further
+ * explanations:
+ *
+ * {i2c_chip} is the I2C chip address (the first byte sent on the bus).
+ *   Each I2C chip on the bus has a unique address.  On the I2C data bus,
+ *   the address is the upper seven bits and the LSB is the "read/write"
+ *   bit.  Note that the {i2c_chip} address specified on the command
+ *   line is not shifted up: e.g. a typical EEPROM memory chip may have
+ *   an I2C address of 0x50, but the data put on the bus will be 0xA0
+ *   for write and 0xA1 for read.  This "non shifted" address notation
+ *   matches at least half of the data sheets :-/.
+ *
+ * {addr} is the address (or offset) within the chip.  Small memory
+ *   chips have 8 bit addresses.  Large memory chips have 16 bit
+ *   addresses.  Other memory chips have 9, 10, or 11 bit addresses.
+ *   Many non-memory chips have multiple registers and {addr} is used
+ *   as the register index.  Some non-memory chips have only one register
+ *   and therefore don't need any {addr} parameter.
+ *
+ *   The default {addr} parameter is one byte (.1) which works well for
+ *   memories and registers with 8 bits of address space.
+ *
+ *   You can specify the length of the {addr} field with the optional .0,
+ *   .1, or .2 modifier (similar to the .b, .w, .l modifier).  If you are
+ *   manipulating a single register device which doesn't use an address
+ *   field, use "0.0" for the address and the ".0" length field will
+ *   suppress the address in the I2C data stream.  This also works for
+ *   successive reads using the I2C auto-incrementing memory pointer.
+ *
+ *   If you are manipulating a large memory with 2-byte addresses, use
+ *   the .2 address modifier, e.g. 210.2 addresses location 528 (decimal).
+ *
+ *   Then there are the unfortunate memory chips that spill the most
+ *   significant 1, 2, or 3 bits of address into the chip address byte.
+ *   This effectively makes one chip (logically) look like 2, 4, or
+ *   8 chips.  This is handled (awkwardly) by #defining
+ *   CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW and using the .1 modifier on the
+ *   {addr} field (since .1 is the default, it doesn't actually have to
+ *   be specified).  Examples: given a memory chip at I2C chip address
+ *   0x50, the following would happen...
+ *     i2c md 50 0 10   display 16 bytes starting at 0x000
+ *                      On the bus: <S> A0 00 <E> <S> A1 <rd> ... <rd>
+ *     i2c md 50 100 10 display 16 bytes starting at 0x100
+ *                      On the bus: <S> A2 00 <E> <S> A3 <rd> ... <rd>
+ *     i2c md 50 210 10 display 16 bytes starting at 0x210
+ *                      On the bus: <S> A4 10 <E> <S> A5 <rd> ... <rd>
+ *   This is awfully ugly.  It would be nice if someone would think up
+ *   a better way of handling this.
+ *

+	 * Notes:	For best results, the selected base
+	 *              address should have enough LSB 0's to
+	 *              guarantee single address bit changes.
+	 *              For example, to test a 64-Kbyte

+ *
+ * With "-c" and size is NOT given, then the export command will
+ * format the data as currently used for the persistent storage,
+ * i. e. it will use CONFIG_ENV_SECT_SIZE as output block size and
+ * prepend a valid CRC32 checksum and, in case of resundant
+ * environment, a "current" redundancy flag. If size is given, this
+ * value will be used instead of CONFIG_ENV_SECT_SIZE; again, CRC32
+ * checksum and redundancy flag will be inserted.
+ *
+ * With "-b" and "-t", always only the real data (including a
+ * terminating '\0' byte) will be written; here the optional size
+ * argument will be used to make sure not to overflow the user
+ * provided buffer; the command will abort if the size is not
+ * sufficient. Any remainign space will be '\0' padded.
+ *
+ * On successful return, the variable "filesize" will be set.
+ * Note that filesize includes the trailing/terminating '\0' byte(s).
