115924b6bdc7cc Shreyas Bhatewara 2009-11-16 212 * The device expects the bitfields in shared structures to be written in
115924b6bdc7cc Shreyas Bhatewara 2009-11-16 213 * little endian. When CPU is big endian, the following routines are used to
115924b6bdc7cc Shreyas Bhatewara 2009-11-16 214 * correctly read and write into ABI.
115924b6bdc7cc Shreyas Bhatewara 2009-11-16 215 * The general technique used here is : double word bitfields are defined in
115924b6bdc7cc Shreyas Bhatewara 2009-11-16 216 * opposite order for big endian architecture. Then before reading them in
115924b6bdc7cc Shreyas Bhatewara 2009-11-16 217 * driver the complete double word is translated using le32_to_cpu. Similarly
115924b6bdc7cc Shreyas Bhatewara 2009-11-16 218 * After the driver writes into bitfields, cpu_to_le32 is used to translate the
115924b6bdc7cc Shreyas Bhatewara 2009-11-16 219 * double words into required format.
115924b6bdc7cc Shreyas Bhatewara 2009-11-16 220 * In order to avoid touching bits in shared structure more than once, temporary
115924b6bdc7cc Shreyas Bhatewara 2009-11-16 221 * descriptors are used. These are passed as srcDesc to following functions.
